To solve a system of equations means to obtain a common values of the variables that makes the ea For these reasons, we rarely use graphing to solve systems. This includes In the substitution method, you solve for one variable and then substitute that expression into the other equation. In some cases you will be dealing with incredibly complex problems, and it may be easier to substitute a variable, like y for part of the problem. There are two approaches and the first approach is called substitution. Instead, we use an algebraic approach.
