Question

-12x + 18 – 10x – 5 = -31

Answer 1

Your answer is x = 2

Step-by-step explanation:
`-12x + 18-10x-5 = -31`

subtract 18 - 5 = 13 and add -12x+(-10x)= -22x

`-22x+13=-31` subtract 13 on both sides

`-22x+13(-13)=-31(-13)` cross out +13(-13) and -31-13= -44

`-22x=-44` divide -22 on both sides

`(-22x)/(-22) = (-44)/(-22)` cross -22x/-22 and divide -44 and -22= 2

`x = 2`

Answer 2

22

Explanation:

Step 1:

- 12x + 18 - 10x - 5 = - 31

Step 2:

- 22x + 18 - 5 = -31

Step 3:

- 22x + 13 = - 31

Step 4:

- 22x = - 44

Answer:

x = 22
