x=13/9 or 1.44

Explanation:

Distribute the 27 throughout the set of parenthesis

*Remember that all whole numbers are actually fractions over 1. And to multiply fractions, multiply numerator (top) by numerator and denominator (bottom) by denominator

27/3x-27/9=10

Simplify the fractions

9x-3=10

Begin to isolate x by adding 3 on both sides of the equation

9x=13

Isolate x by dividing both sides of the equation by 9

x=13/9 or 1.44
