Let's solve for x the following question:

3/4 (x - 16) = 5/4 (2x - 32)

As I told you on the previous exercise:

Step 1: Solve the parenthesis

3/4 x - 48/4 = 10/4 x - 160/4

Step 2: Like terms

3/4x - 10/4x = -160/4 + 48/4

-7/4x = -112/4

Step 3: Simplifying

-7/4x = -28

Step 4: Multiplying by 4 at both sides:

-7/4x * 4 = -28 * 4

-7x = -112

-7x/-7 = -112/-7

x = 16
