Answer: x > 69/25

Explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "5.06" was replaced by "(506/100)". 2 more similar replacement(s)

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

x+(23/10)-((506/100))>0

Step by step solution :

Step 1 :

253

Simplify ———

50

Equation at the end of step 1 :

23 253

(x + ——) - ——— > 0

10 50

Step 2 :

23

Simplify ——

10

Equation at the end of step 2 :

23 253

(x + ——) - ——— > 0

10 50

Step 3 :

Rewriting the whole as an Equivalent Fraction :

3.1 Adding a fraction to a whole

Rewrite the whole as a fraction using 10 as the denominator :

x x • 10

x = — = ——————

1 10

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:

x • 10 + 23 10x + 23

——————————— = ————————

10 10

Equation at the end of step 3 :

(10x + 23) 253

—————————— - ——— > 0

10 50

Step 4 :

Calculating the Least Common Multiple :

4.1 Find the Least Common Multiple

The left denominator is : 10

The right denominator is : 50

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 1 1

5 1 2 2

Product of all

Prime Factors 10 50 50

Least Common Multiple:

50

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 = 5

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. (10x+23) • 5

—————————————————— = ————————————

L.C.M 50

R. Mult. • R. Num. 253

—————————————————— = ———

L.C.M 50

Adding fractions that have a common denominator :

4.4 Adding up the two equivalent fractions

(10x+23) • 5 - (253) 50x - 138

———————————————————— = —————————

50 50

Step 5 :

Pulling out like terms :

5.1 Pull out like factors :

50x - 138 = 2 • (25x - 69)

Equation at the end of step 5 :

2 • (25x - 69)

—————————————— > 0

50

Step 6 :

6.1 Multiply both sides by 50

6.2 Divide both sides by 2

6.3 Divide both sides by 25

x-(69/25) > 0
