A way to solve a linear system algebraically is to use the
substitution method. The substitution method functions by
substituting the one y-value with the other. We're going
to explain this by using an example.
We can substitute y in the second equation with the first
equation since y = y.
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.
