43 = 7 - 3x(-12) 

First distribute the -3x

By distributing, you should get

43 = 7 + 36x now subtract 7 on both sides

By subtracting, you should get

36 = 36x divide both sides by 36

By dividing, you should get

X = 1 which is your answer

`43 = 7 - 3x(-12)`

`43 = 7+36x`  combine like terms

`43-7=36x`

`36=36x`

`36/36 = (36x)/36`    1=x
