X+y=-9. 5x-2y=32. elimination using manipulation

x=2, y=11.

Step-by-step explanation:

x + y = -9.  

5x - 2y = 32   Multiply the first equation by 2:

2x + 2y = -18   Adding the last 2 equations to eliminate y:

7x =  14

x = 2,

Substitute x = 2 in the first equation:

2 + y = -9

y = -9 - 2

y = -11.
