Consider if ax+b= cx+d was given as an equation with variables on both sides. One could form and solve the following system of linear equations.
y= ax+b
y= cx+d
The solution to such a system can be found both algebraically and graphically. Solving algebraically, the goal would be to isolate the value of x using either the Substitution Method or the Elimination Method. When solving graphically, the solution is the x-value of the point of intersection of the lines of both graphs.
