Andre is trying to solve this system of equations: x+y = 3 4x = 12 - 4y Looking at the first equation, he thought, "The solution to the system is a pair of numbers that add up to 3. I wonder which two numbers they are." 1) Choose any two numbers that add up to 3. Let the first one be the x-value and the second one be the y-value.
