Question

Solve 7 + x - 15 = -2 2/3

Answer 1

first combine like terms
7 + x - 15 = -2 2/3
-8 + x = -2 2/3 (add 8 to both sides)
x = -2 2/3 + 8 (turn your mixed fraction to an improper fraction)
x = - 8/3 + 8 (common denominator is 3)
x = -8/3 + 24/3
x = 16/3 or 5 1/3

check...
-8 + x = 8/3
-8 + 16/3 = - 8/3
-24/3 + 16/3 = -8/3
-8/3 = -8/3 (correct)

x = 16/3 or 5 1/3
