Solve the following system of equation using the substitution or elimination method. Show your work! Y = 3x -9
Y= -2x +1​

Step-by-step explanation:

I'll be using substitution to solve this since it's easier. Since y = 3x - 9, I can plug that into the y for the other equation and vice versa.

1.) Cancel out -2x on the right side by adding it on both sides.

2.) Cancel out -9 on left side by adding it on both sides.

3.) Divide both sides by 5 to isolate and solve for x.

4.) Plug x into one of the equations to solve for y.

5.) Solve.

Solution: (2, -3)
