Answer: X = -7
Step-by-step explanation:
5(-2x-3)-4x-5=78
We move all terms to the left:
5(-2x-3)-4x-5-(78)=0
We add all the numbers together, and all the variables
-4x+5(-2x-3)-83=0
We multiply parentheses
-4x-10x-15-83=0
We add all the numbers together, and all the variables
-14x-98=0
We move all terms containing x to the left, all other terms to the right
-14x=98
x=98/-14
x=-7
