Please read my workings in the attached image
the arrows mean "the previous line leads to this line"
the 3 dots means "therefore’
<span>If you would like
to know the values of these two numbers, you can calculate this using the following
steps:<span>
a + b = 77.95
a - b = </span></span>30.61 ... a = 30.61 + b
________<span>_______________
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 = </span>47.34<span> / 2
b = 23.67
a = </span>30.61 + b = 30.61 + 23.67<span> = 54.28
Result:
The numbers are </span>23.67<span> and 54.28.</span>
