System of Equations by substution

In this game, you'll put your substitution skills to the test. Here's how to play:
Solve for the "y" variable: Isolate the y-variable in both equations.
Substitute: Set each x-expression equal to each other.
Solve for x: Solve the equation with variables on both sides for x.
Substitute back: Substitute the x value you found back into both equations to see the value of the other variable.
Check your solution: Verify that the values you found satisfy both original equations.
