Answer 1

–x + y = –3 (a)
3x + 2y = 9 (b)

Lt's eliminate y , by multiplying a) by -2

-2(–x + y) = -2(–3) → +2x - 2y = +6 (c). Now add (c) to (b)

+2x - 2y = +6 (c).
3x + 2y = 9 (b)
-----------  --------
5x + 0   = 15     and x = 15/5   and x = 3
To find y, plugin the value of x in any of the equation, sat (a):
–x + y = –3 (a) → -3 + y = -3; y = -3+3 → y = 0

So the solution is (3,0) Answer C
