Question

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

Did i do this correctly?

Answer 1

Nope, not really.
For the step ''x + 10 + 4x = 10'', it should be x -10 + 4x. since -2(5) = -10

Answer 2

So i didnt distribute correctly?

Answer 3

I'm sorry but you didn't distribute correctly.

Answer 4

Okay, thanks!

Answer 5

Welcome. Since you've got that step wrong, the rest are incorrect too.. So, just start solving x from that step. Good luck :)
