Breann solved the system of equations below. What mistake did she make in her work? 2x + y = 5 x − 2y = 10 y = 5 − 2x x − 2(5 − 2x) = 10 x − 10 + 4x = 10 5x − 10 = 10 5x = 20 x = 4 2(4) + y = 5 y = −3 She should have substituted 5 + 2x She combined like terms incorrectly, it should have been 4x instead of 5x She subtracted 10 from both sides instead of adding 10 to both sides She made no mistake
