Answer: x=4
Explanation:
Step 1. turn you y into a 0
0=4x-16
Step 2. get x alone
a.
0 = 4x -16
+16 +16
*what you do to one side of the equal sign you must to the other.
b.
0 + 16 = 4x
(divide by 4) 16 = 4x (divide by 4)
*divide by 4 to get rid of the 4 next to the x, remeber to do both sides of the equal sign
4 = x
