The Sum Of Two Numbers Is 46 And Their Difference Is 7

The problem given says that 2 unknown numbers are given, whose sum is equal to 46 and the difference is 7. Let's find the two numbers :

When we add the two numbers :
X + Y = 46

The difference of two numbers :
X - Y = 7

Solution :

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

X + Y = 46
X - Y = 7

2X = 53

Let's divide 53 to 2 for the first number "X" .

X/2 = 26.5

First number is 26.5

X + Y = 46
So ;
26.5 + Y = 46
Y = 46 - 26.5
Y = 19.5

Second number is 19.5

Question & Answer
The Sum Of Two Numbers Is 46 And Their Difference Is 7 : 26.5 And 19.5
