Solve linear equation by substitution
WebThe substitution method is most useful for systems of 2 equations in 2 unknowns. The main idea here is that we solve one of the equations for one of the unknowns, and then substitute the result into the other equation. Substitution method can be applied in four steps. Step 1: Solve one of the equations for either x = or y =. Step 2: WebGood evening.
