What is 5x/7 - 12 = x?
5x divided by 7 minus 12 equals x?
5x/7 - 12 = x
7(5x/7 - 12) = x * 7
5x - 84 = 7x
5x - 84 - 7x = 7x - 7x
-2x - 84 = 0
-2x - 84 + 84 = 0 + 84
-2x = 84
-2x / -2 = 84 / -2
x = -42
Check the answer
5x/7 - 12 = x
5(-42)/7 - 12 = -42
5(-42/7) - 12 = -42
5(-6) - 12 = -42
-30 - 12 = -42
-42 = -42
Answer: x = -42
