You have to isolate x on one side.
27x - 3.2x = 9.6 - 3 (Get all the x terms on one side and the numbers on the other).
23.8x = 6.6 (Combine the numbers).
x = 6.6 ÷ 23.8 (Isolate x)
x is approximately equal to 0.2773, round as needed.
To check, simply substitute the answer in for x and make sure both sides are equal.
