Equations With Two Variables When an equation has on variable, a solution is a value for the variable that makes the equation true. When an equation has two variables, a solution is an ordered pair that makes the equation true. To find the solution of an equation with two variables, you must choose values for one of the variables and then solve for the corresponding values of the other variables. -Linear Equations (Math is Fun): Click Here -Solutions to 2-Variable Equations (Khan Academy): Click Here
