The Sum Of Two Numbers Is 76 And Their Difference Is 10

The problem given says that 2 unknown numbers are given, whose sum is equal to 76 and the difference is 10. Let's find the two numbers :

When we add the two numbers :
X + Y = 76

The difference of two numbers :
X - Y = 10

Solution :

If we add the two equations eachother , then we can find the first number.

X + Y = 76
X - Y = 10

2X = 86

Let's divide 86 to 2 for the first number "X" .

X/2 = 43

First number is 43

X + Y = 76
So ;
43 + Y = 76
Y = 76 - 43
Y = 33

Second number is 33
