If you would like
to know the values of these two numbers, you can calculate this using the following
steps:
a + b = 77.95 a - b = 30.61 ... a = 30.61 + b _______________________
a + b = 77.95 (30.61 + b)
+ b = 77.95 30.61 + 2 *
b = 77.95
2 * b =
77.95 - 30.61
2 * b
= 47.34 /2
b = 47.34 / 2 b = 23.67
