Answer: -11, -3, 17
Step-by-step explanation:
There are three answers depending on what x equals. In this case, x can equal: -2, 0, or 5.
Part 1:
Step 1: Substitute -2 for x
-3 + 4(2)
Step 2: Solve
-3 + 8 = 5
This is the first answer
Part 2:
Step 1: Substitute 0 for x
-3 + 4(0)
Step 2: Solve
-3 + 0 = -3
This is the second answer
Part 3:
Step 1: Substitue 5 for x
-3 + 4(5)
Step 2: Solve
-3 + 20 = 17
This is the third answer
