Question 233242
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
