Answer: x = -1.8
Step-by-step explanation:
-7 - 12 = -7x + 3 (-4 - x)
-7x + 3 (-4 - x) = -7 - 12
P.S I switched the order cuz I find it easier to solve this way.
-7x + 3 (-4 - x) = -7 - 12
Distribute
-7x - 12 - 3x = - 7 + 13
Add 12 to both sides
-7x - 3x = -7 + 13 + 12
Combine like terms
-10x = 18
Divide both sides by -10
x = -1.8
