Answer:

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

13-(x/4)=0

Step by step solution :

Step 1 :

x

Simplify —

4

Equation at the end of step 1 :

x

13 - — = 0

4

Step 2 :

Rewriting the whole as an Equivalent Fraction :

2.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using 4 as the denominator :

13 13 • 4

13 = —— = ——————

1 4

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 :

2.2 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:

13 • 4 - (x) 52 - x

———————————— = ——————

4 4

Equation at the end of step 2 :

52 - x

—————— = 0

4

Step 3 :

When a fraction equals zero :

Now, to get rid of the denominator, Tiger multiple's both sides of the equation by the denominator. 3.1 When a fraction equals zero …

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

Here's how:

52-x

———— • 4 = 0 • 4

4

Now, on the left hand side, the 4 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

52-x = 0

Solving a Single Variable Equation :

3.2 Solve : -x+52 = 0

Subtract 52 from both sides of the equation :

-x = -52

Multiply both sides of the equation by (-1) : x = 52
