The Sum Of Two Numbers Is 88 And Their Difference Is 28
The problem given says that 2 unknown numbers are given, whose sum is equal to 88 and the difference is 28. Let's find the two numbers :When we add the two numbers :
X + Y = 88
The difference of two numbers :
X - Y = 28
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 88 X - Y = 28 2X = 116 |
Let's divide 116 to 2 for the first number "X" .
X/2 = 58
First number is 58
X + Y = 88
So ;
58 + Y = 88
Y = 88 - 58
Y = 30
Second number is 30
Question & Answer
