The goal of solving a linear equation is to find the value of the variable that will make the statement (equation) true. With graphs), focusing on pairs of linear equations in two variables. Make sure to interpret your results (ex: 3) once you solved one for one of the variables, plug this solution into one of the original equations and solve for the other. 3 4 x − 7 2 = 5 6.
