Solve the system by substitution.<br> y = 5x<br> y = 9x + 8
Ymorist [56]

Answer:

(-2,-10)

Step-by-step explanation:

So if y=5x and if y=9x+8 then those should be able to equal each other (substitution):

5x=9x+8

Subtract 5x from both sides:

0=4x+8

Subtract 8 from both sides:

-8=4x

Divide both sides by 4:

x=-2

If x=-2, then we can just plug it back into the first equation:

y=5(-2)

Simplify:

y=-10
