Trevor solved the system of equations below. What mistake did he make in his work?
2x + y = 5
x  2y = 10
y = 5  2x
x  2(5  2x) = 10
x  10 + 4x = 10
5x  10 = 10
5x = 0
x = 0
2(0) + y = 5
y = 5
Answer
He made no mistake
He combined like terms incorrectly, it should have been 4x instead of 5x
He should have substituted 5 + 2x
He subtracted 10 from the right side instead of adding 10 to the right side
