Answer:
-17
Step-by-step 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:
