There is three ways to solve a system of 2 equations. The first is by graphing, or just putting the 2 equations into desmos and seeing where the lines cross. The second is substitution, when using substitution you solve one of the equations then plug it back into the other equation. The third is elimination. Elimination is when you either add or subtract the 2 equations to get one of the variables. My favorite is graphing because its the easiest.
