Answer 2

Step-by-step explanation:

Vanessa is trying to solve the equation for x.

The given equation is -3 + 4x = 9, or 4x - 3 = 9

She shouldn't be subtracting any number in the beginning. Instead, she should do the opposite of PEMDAS:

1) Vanessa should add 3 to both sides:

4x - 3 (+3) = 9 (+3)

4x = 9 + 3

4x = 12

2) Next, she should divide 4 from both sides:

(4x)/4 = (12)/4

x = 12/4

x = 3

Vanessa's answer will be x = 3.
