Lets denote the numbers x and y:
The sum of two numbers 94 → x + y = 94
Their difference is 12 → x - y = 12
We have:
x + y = 94
x - y = 12
---------------- Add both equations
2x = 106
x = 106/2
x = 53
Using first equation:
x + y = 94
53 + y = 94
y = 94 - 53
y = 41
A/ The numbers are 53 and 41.
Pretty easy my friend, consider the two numbers we want x and y
x + y = 94
x - y = 12
Now you solve the system
x = 94 - y
94 - y - y = 12
x = 94 - y
94 - 2y = 12
x = 94 - y
- 2y = 12 - 94
x = 94 - y
- 2y = - 82
x = 94 - y
2y = 82
x = 94 - y
y = 41
x = 94 - 41
y = 41
x = 53
y = 41
x + y = 94
x - y = 12
Now you solve the system
x = 94 - y
94 - y - y = 12
x = 94 - y
94 - 2y = 12
x = 94 - y
- 2y = 12 - 94
x = 94 - y
- 2y = - 82
x = 94 - y
2y = 82
x = 94 - y
y = 41
x = 94 - 41
y = 41
x = 53
y = 41
