Question

How do you solve 2z-31=-9z+24

Answer 1

You drop a line down from the equals sign you subtract 9 Z from 2 Z and you get 7 Z - 31 = 24 then you add 31 to 24 and you get 7 Z = 55 you then divide the 7 from 7 Z and 55 then your answer will be Z=55/7

Answer 2

2z-31 = -9z+24

First, combine like terms: 11z = 55

Then, divide both sides by 11: 11z/11 = 55/11

Simplify: z=5
