Multiply the top numbers by -2. That’ll give you: -2x - 6y = 24 2x - y = -3 That’ll end up with: -7y = 21 And you must get y by itself. So you divide -7y by -7 and that means you need to divide 21 by -7 as well. So that means: y = -3 Now you need to plug it into one of those equations to find the answer for x Let’s do 2x - y = -3 2x + 3 = -3 Since subtracting negatives is the same as adding a positive we used a plus sign. Get 2x by itself 2x = -6 x = -3 (-3, -3)
