Y= -x+2 x-3y =-18 how do i solve these so i can graph them

1. Substitute y=-x+2 into x-3y=-18:

x-3(-x+2)=-18,

x+3x-6=-18,

x+3x=-18+6,

4x=-12,

x=-3.

Then y=-(-3)+2=3+2=5.

2. The graphs of two equations you can see in attached diagram. Common point (the point of intersection) represents the solution of the system of two equations.

(-3,5) or x=-3, y=5.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
