of Equations There are generally two approaches to solving systems of equations in physics, the substitution method and the addition method. Let us consider the system of two equations below: 4x + 2y 14 2x -y-1 We can solve these equations using both methods. First, the substitution method. The process is as follows: In one of the equations, solve for one of the variables . te this expression for that variable into the other equation. This will leave an expression...
