7 = -9 + 4x
Add 9 to both sides, which gives you:
16 = 4x
Now divide both sides by 4, which gives you:
4 = x.
So the answer is x = 4.

7=-9+4x add 9 to both sides
16=4x now divide by 4 to isolate the x
4=x

Sure I can answer that for you...
7 = -9 + 4X
7 + 9 = -9 + 9 + 4X
16 = 4X
16 / 4 = 4X / 4
4 = x
Answer: X = 4
