Answer:
In other words, x plus y equals 21 and can be written as equation A:
x + y = 21. The difference between x and y is 5. In other words, x minus y equals 5 and can be written as equation B:
x - y = 5.
x - y = 5. x = 5 + y.
x + y = 21. 5 + y + y = 21. 5 + 2y = 21. ...
x + y = 21. x + 8 = 21. ...
Sum: 13 + 8 = 21. Difference: 13 - 8 = 5.
