From the first equation by adding to both sides y you get x = 17 + y. Next try to substitute obtained equation for x in the second equation.

Here is an example:
x + y = 5 2 x + 3 y = 10
There are 2 ways I might try to solve this. The first equation tells me that x = 5 y. The second tells me that 2 x + 3 y = 10, so plugging in for x, I get that 2 ( 5 y ) + 3 y = 10 2 y + 3 y = 10 + y = 10. And thus y = 0. Then we also get (from either original equation) that x = 5.
The other way might be to notice that x + y = 5 is the same as 2 x + 2 y = 10. So then I might subtract 2 x + 2 y = 10 from 2 x + 3 y = 10 to see that ( 2 x + 3 y ) ( 2 x + 2 y ) = y = 0 = ( 10 10 ). And again, y = 0, x = 5.
Can you apply these methods to this system?
