Add the equations to eliminate x.

This will allow you to quickly solve for y. 

Answer:

Add the equations to eliminate x

Step-by-step explanation:

y = x + 12..... equation 1

y = −x + 17 .... equation 2

Adding equation 1 and equation 2 gives 2Y = 29....X has been eliminated

Y = 14.5

Substituting value of Y in equation 1

14.5 = x+12

X= 2.5

So

Y = 14.5

X= 2.5
