Answer:

[tex]x=-7[/tex]

Step-by-step explanation:

We want to solve

5(-2x-3) - 4x -5 =78

We expand to get:

[tex]-10x-15-4x-5=78[/tex]

We group the similar terms to get:

[tex]-10x-4x=78+20[/tex]

Combine similar terms

[tex]-14x=98[/tex]

Divide through by -14

[tex]x=\frac{988}{-14}=-7[/tex]
