how to solve for 2 variables Add the equations resulting from Step 2 to eliminate one variable Solve for the remaining variable Substitute the solution from Step 4 into one of the original equations Then solve for the other variable Write the solution as
To solve a system of two linear equations we want to find the values of the variables that are solutions to both equations In other words we are looking for the ordered pairs x y that make both equations true These Step 1 Solve one of the equations for one variable Step 2 Substitute this in the other equation to get an equation in terms of a single variable Step 3 Solve it for the variable Step 4 Substitute it in any of the equations to get the value of
