The Sum Of Two Numbers Is 88 And Their Difference Is 30
The problem given says that 2 unknown numbers are given, whose sum is equal to 88 and the difference is 30. Let's find the two numbers :When we add the two numbers :
X + Y = 88
The difference of two numbers :
X - Y = 30
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 88 X - Y = 30 2X = 118 |
Let's divide 118 to 2 for the first number "X" .
X/2 = 59
First number is 59
X + Y = 88
So ;
59 + Y = 88
Y = 88 - 59
Y = 29
Second number is 29
Question & Answer
