We are given the following two equations
[tex]7x-2y=-13\qquad eq.1[/tex][tex]x-2y=11\qquad eq.2[/tex]In the substitution method, we separate a variable in one equation and substitute it into the other equation.
Let us separate the variable x in eq.2
[tex]\begin{gathered} x-2y=11 \\ x=11+2y \end{gathered}[/tex]Now let us substitute the above value of x into the eq.1
