Answer:

-17

Explanation:

First, we want to solve for x in -3x-7=5.

-3x-7=5 Add 7 on both sides.

+7 +7

-3x=12 Divide by -3 on both sides.

/-3 /-3

x=-4

Since we have the answer for this equation, we have to substitute x with -4 in 5x+3.

5(-4)+3 Using the order of operations, we multiply before adding.

-20+3 5(-4)=-20...now we can add.

=-17

Hop this helped!! Have a nice day C:
