how to solve for x and y in one equation Assuming you have two equations the best way for solving for both variables is to use the substitution method which involves solving for one variable as far as possible then plugging it back in to the other equation
You know that x 2 and one of your original equations is 3x y 3 Plug in 2 instead of x 3 2 y 3 Solve for y in the equation 6 y 3 6 y y 3 y so 6 3 y 3 y Plug x 3 into the equation x 6y 4 to solve for y 3 6y 4 6y 1 Divide 6y and 1 by 6 to get y 1 6 You have solved the system of equations by addition x y 3 1 6

Example solve for x 2xx 3 3 6x 3 x 3 We have said x 3 to avoid a division by zero Let s multiply through by x 3 2x 3 x 3 6 Bring the 6 to the left 2x 3 x 3 6 0 Expand and solve 2x 3x 9 6 0 5x 15 0 5 x 3 0 x 3 0 Which can be solved by having x 3 In order to use the substitution method we ll need to solve for either x or y in one of the equations Let s solve for y in the second equation 2 x y 9 y 2 x 9 Now we can substitute the expression 2 x 9 in for y in the first equation of our system
