Question

What is the solution of the system? Use substitution.
y= 4x + 4
y = 5x

Answer 1

Answer:

x = 4, y = 20

Step-by-step explanation:

Substitute y = 5x into y = 4x + 4.

This would be:

$5x = 4x+4$

subtract 4x from both sides

$x=4$

Then, substitute x = 4 into the equation y = 5x

$y = 5 * 4\\y = 20$
