Answer:
x = 30
y = 20
or
(30 , 20)
Step-By-Step:
We can start my setting up a system of equations. Like this.
x + y = 50
x - y = 10
We can solve by adding down the two equations so that one of the variables cancels out being the y.
The new equation will be:
2x = 60
So x = 30
Now plug x back into either equation and solve for y.
30 + y = 50
Solve for y.
y = 20
