X - y =2 X + y= -3<br> What is (x,y)
Dimas [21]

Answer:

(-1/2,-5/2)

Step-by-step explanation:

x-y = 2

x+y = -3

---------------

Through Elimination, we can just add the system of equations. The y cancels out and gives us the single equation for x:

2x = -1

x = -1/2

Substitute -1/2 for x in either equation and you get:

(-1/2) + y = -3     Solve for y

y = -5/2
