Question

Solve the following algebraically
X+2y=17
X-y=2 can you pls leave the steps of how to complete this problem

Answer 1

come on, this is just Algebra I all over again.

From the first equation, x = 17-2y

Plug that into the 2nd equation and you have

17-2y-y=2
-3y=-15
y=5

Or, from the 2nd equation, x=y+2, so
y+2+2y=17
3y=15
y=5

Or, just subtract the 2nd from the first, and you get

3y=15
y=5

In any case, now you can easily find x.
