Answer:
58 and 29
Step-by-step explanation:
Set up your equations:
1) x + y = 87
2) x - y = 29
Use one of the equations to focus on when moving the numbers around such as for this one I used equation one:
3) y = -x + 87
x = (-x + 87) + 29
x = -x + 116
x + x = 116
2x = 116
x = 58
Input your value for x:
4) 58 + y = 87
y = 87 - 58
y = 29
Solve and check if your values are correct:
5) 58 + 29 = 89 correct
58 - 29 = 29 correct
