Question

The sum of two numbers is 98. their difference is 22. write a system of equations that describes this situation. solve by elimination to find the two numbers. algebra.com

Answer 1

Y+x=98
y-x=22

I'm going to use elimination. 

y+x=98
y-x=22
-----------
2y+0x=120 SIMPLIFY 2y=120 SIMPLIFY y=60. 

Substitute that into either equation and you get y=60 and x=38

Have a nice day! :)
