X-=5y-1
x+2y=13
how do you get the answer? every time i got the answer i got it wrong

The first one has a negative. You shouldn't have a negative isolated variable,
-x = 5y -1, Multiply everything by -1,
x = -5y + 1,

For the second one, you isolate the x,
x + 2y = 13, subtract 2y from both sides,
x = 13 - 2y.

B.-2,3 because it is touch the -3 i think that the answer

Figure it out your self
