The Sum Of Two Numbers Is 90 And Their Difference Is 24
The problem given says that 2 unknown numbers are given, whose sum is equal to 90 and the difference is 24. Let's find the two numbers :When we add the two numbers :
X + Y = 90
The difference of two numbers :
X - Y = 24
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 90 X - Y = 24 2X = 114 |
Let's divide 114 to 2 for the first number "X" .
X/2 = 57
First number is 57
X + Y = 90
So ;
57 + Y = 90
Y = 90 - 57
Y = 33
Second number is 33
Question & Answer
The Sum Of Two Numbers Is 90 And Their Difference Is 24 : 57 And 33
