You can put this solution on YOUR website!
x+y=129
x-y=61
Use substitution method to solve.
I'll use x-y=61 to solve for x
x=y+61
substitute this into the 1st equation to solve for y.
y+61+y=129
2y=68
y=34
substitute this into the 1st solution..
x=34+61
x=95
so x=95 and y=34
plug both numbers into the original equations to verify
