HI!!

misty1212 · Answer

$$y = x^2 − 4x + 8\
4x + y = 12
$$ right?

qwertty123 · Answer

I am not sure if the x is ^ or just being multiplied. @Motown117

Solve the second equation for y and plug this into the first equation
Solve for. X
Then unplug this value of x into second equation to find  y
