You need to add the equations together to eliminate one variable. You may need to first multiply one or both equations by factors to eliminate a variable. Look at both equations, if you add them, you'll get 7x + y = 2. No variable was eliminated. That means you need to multiply. Let's eliminate the x variable. 1. Multiply the first equation by 5 and the second equation by 2: 5(2x + 6y) = 5(12) 2(5x  5y) = 2(10) 10x  30y = 60 10x  10y = 20 Now add them: 40y = 80 Solve: y = 2 You can now plug in y = 2 into one of the original equations to get x.
