-6x + 6y =6 -6x + 3y = -12 You would multiply the bottom equation by -1 to make -6x a positive so you can eliminate it. -6x + 6y = 6 6x + -3y = 12 Eliminate -6y and add 6y to -3y as well as 6 and 12. 0 + 3y = 18 3y = 18 divide both sides by 3 y = 6
now that you know the value of y it will be easy to find x :)
