2x, and then replace y in the second by this. 2x 3(12 2x) = 4. Now we solve this equation for x, first simplifying to get 2x 36 + 6x = 4, or 8x = 40, so that x = 5. The corresponding y is y = 12 2(5) = 2. Note another way to solve the equation: subtract the second equation from the first to get 4y = 8, and thus y = 2.
