Carlos solved the system of equations below. what mistake did he make in his work? (5 points) 2x + y = 5 x β 2y = 10 y = 5 β 2x x β 2(5 β 2x) = 10 x + 10 + 4x = 10 5x + 10 = 10 5x = 0 x = 0 2(0) + y = 5 y = 5 he should have substituted 5 + 2x he did not distribute correctly he combined like terms incorrectly, it should have been 4x instead of 5x he made no mistake
