Answer:

(225/10)+x=-(4737/100)

One solution was found :

x = -6987/100 = -69.870

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "47.37" was replaced by "(4737/100)". 2 more similar replacement(s)

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

(225/10)+x-(-(4737/100))=0

Step by step solution :

Step 1 :

4737

Simplify ————

100

Equation at the end of step 1 :

225 4737

(——— + x) - (0 - ————) = 0

10 100

Step 2 :

45

Simplify ——

2

Equation at the end of step 2 :

45 -4737

(—— + x) - ————— = 0

2 100

Step 3 :

Rewriting the whole as an Equivalent Fraction :

3.1 Adding a whole to a fraction

Rewrite the whole as a fraction using 2 as the denominator :

x x • 2

x = — = —————

1 2

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

45 + x • 2 2x + 45

—————————— = ———————

2 2

Equation at the end of step 3 :

(2x + 45) -4737

————————— - ————— = 0

2 100

Step 4 :

Calculating the Least Common Multiple :

4.1 Find the Least Common Multiple

The left denominator is : 2

The right denominator is : 100

Number of times each prime factor

appears in the factorization of:

Prime

Factor Left

Denominator Right

Denominator L.C.M = Max

{Left,Right}

2 1 2 2

5 0 2 2

Product of all

Prime Factors 2 100 100

Least Common Multiple:

100

Calculating Multipliers :

4.2 Calculate multipliers for the two fractions

Denote the Least Common Multiple by L.C.M

Denote the Left Multiplier by Left_M

Denote the Right Multiplier by Right_M

Denote the Left Deniminator by L_Deno

Denote the Right Multiplier by R_Deno

Left_M = L.C.M / L_Deno = 50

Right_M = L.C.M / R_Deno = 1

Making Equivalent Fractions :

4.3 Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

L. Mult. • L. Num. (2x+45) • 50

—————————————————— = ————————————

L.C.M 100

R. Mult. • R. Num. -4737

—————————————————— = —————

L.C.M 100

Adding fractions that have a common denominator :

4.4 Adding up the two equivalent fractions

(2x+45) • 50 - (-4737) 100x + 6987

—————————————————————— = ———————————

100 100

Equation at the end of step 4 :

100x + 6987

——————————— = 0

100

Step 5 :

When a fraction equals zero :

5.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

100x+6987

————————— • 100 = 0 • 100

100

Now, on the left hand side, the 100 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

100x+6987 = 0

Solving a Single Variable Equation :

5.2 Solve : 100x+6987 = 0

Subtract 6987 from both sides of the equation :

100x = -6987

Divide both sides of the equation by 100:

x = -6987/100 = -69.870

One solution was found :

x = -6987/100 = -69.870
