Question

Solve the system by substitution.
y = 4x + 3
y = 72

Answer 1

17.25

Explanation:

You already know y = 72, so you could rewrite the equation to 72 = 4x + 3. To get to the answer, you need to find what X is. What you should do is subtract 3 from both sides, get 69, divide by 4 on both sides and get 17.25

I'm not sure if this is correct, but I hope this helped.
