Answer:
She should subtract -3 from both sides

Step-by-step explanation:
To solve this problem you need to isolate the variable. To do that, you would first subtract both sides by negative three and then divide both sides by 4.
Here is what that would look like:

-3 + 4x = 9
-3 - (-3) + 4x = 9 - (-3)
4x = 12
4x / 4 = 12 / 4
x = 3

Answer:

subtract -3

Step-by-step explanation:

–3 + 4x = 9

Add 3 to each side

This is the same as subtracting -3

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

4x = 9 +3

4x = 12
