1) Make x the subject in the first equation (solve for x in the first equation)
2) Now that you have x in terms of y, substitute x in equation 2
3) Now you will have an equation with only y, solve for y
4) Once you have y, go back to the first equation with x in terms of y, substitute the y obtained from third step and solve for x
