substituation is easy.

You just have 2 equations and you cancel one varible out and use it to plug back into the equation.

Just describe how you are doing each step.

Be like..I changed 2x to -2x so it will cancel out with the other 2x and added the equations together to cancel out the X's. Math things like that are a pain in the *** but easy.
