Question 70768
the sum of two numbers is 2. if one number is subtracted from the other, their difference is 8. find the numbers.
X+Y=2 
X-Y=8
If you subtract X+Y with X-Y, you get 2y, and so that equals 2-8, that is -6.
2y=-6
y=(-6)/2
y=-3
-3+X=2
x=2+3
x=5 and y=-8 
Check
-3+5=2
5-(-3)=8
WE DID IT! Hope you get better by practicing over time!
