The average of 17 and 15 is 16 because if you add 17 and 15 together, and you divide them by 2, you get 16.
Answer:
Add 7 to both sides
Step-by-step explanation:
You would need to add 7 to both sides to cancel out the 7 on the right side of the equation to get x one step closer to being by itself.
Then you would get 4x = -8.
Next divide by 4 on both sides to get x by itself so do the inverse operation of what 4 was doing to x.
x = -2
Just rotate it 90 degrees clockwise like this
