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
