Answer:
y + 4 = x +8.
y - x = 4
Step-by-step explanation:
This is a rate change equation,
When y increases by 4, the equation to represent that is (y + 4).
When x is also increased by 8, the equation is (x + 8)
Since both equation are dependable,
y + 4 = x + 8
We can further simplify this to
y - x = 8 - 4
y - x = 4.
