The Sum Of Two Numbers Is 70 And Their Difference Is 33

The problem given says that 2 unknown numbers are given, whose sum is equal to 70 and the difference is 33. Let's find the two numbers :

When we add the two numbers :
X + Y = 70

The difference of two numbers :
X - Y = 33

Solution :

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

X + Y = 70
X - Y = 33

2X = 103

Let's divide 103 to 2 for the first number "X" .

X/2 = 51.5

First number is 51.5

X + Y = 70
So ;
51.5 + Y = 70
Y = 70 - 51.5
Y = 18.5

Second number is 18.5
