The Sum Of Two Numbers Is 53 And Their Difference Is 15
The problem given says that 2 unknown numbers are given, whose sum is equal to 53 and the difference is 15. Let's find the two numbers :When we add the two numbers :
X + Y = 53
The difference of two numbers :
X - Y = 15
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 53 X - Y = 15 2X = 68 |
Let's divide 68 to 2 for the first number "X" .
X/2 = 34
First number is 34
X + Y = 53
So ;
34 + Y = 53
Y = 53 - 34
Y = 19
Second number is 19
