QuickMath will automatically answer the most common problems in algebra equations and calculus faced by high-school and college students. Next isolate the variable itself. What can QuickMath do.
Your goal is to get the variable that you are solving for by itself on one side of the equation.
Therefore subtract 8 from both sides. But if you subtract 2x from both sides of the equation the variable term on the right will be cancelled out leaving you with -x 4. Next isolate the variable itself. When a system of equations is simple the easiest way to solve it is by substitution.
