This value of x can then be used to find y by substituting 1 with x e.g. in the first equation. The solution of the linear system is (1, 6). You can use the substitution method even if both equations of the linear system are in standard form. Just begin by solving one of the equations for one of its variables. Video lesson: Solve the linear system using the substitution method. 1  Pre-Algebra. 2  Algebra 1.
