Solve the system of equations.
\begin{aligned} & 12x-5y = -20 & y=x+4 \end{aligned}


12x−5y=−20
y=x+4

x=0 y=4

Step-by-step explanation:

12x−5y=−20

y=x+4

substitute y in the first equation with x+4 (the second equation gives you the value of y straight away)

12x-5*(x+4)=-20

12x-5x-20=-20

7x=0

x=0

use this value of x in the second equation

y=0 + 4 = 4

i dont know

this is false ^.^ lol
