Multiply the second equation by 2 and then subtract the second equation to eliminate the 'y' term. . -3x +4y = 8 2x + 4y = 20 ------------- subtract -5x = -12 x = -12/-5 = 12/5 . Now substitute to find 'y' using the first equation. . -3*(12/5) + 4*y = 8 4y = 8 +36/5 = 40/5 + 36/5 = 76/5 y = 19/5 . Check these values using the second equation to be sure this is the answer. (12/5) + 2*(19/5) = 10 12/5 + 38/5 = 50/5 = 10 Correct. . Answer: x = 12/5, y = 19/5, which can be shown as the ordered point (12/5, 19/5). . Done.
