The Sum Of Two Numbers Is 76 And Their Difference Is 29
The problem given says that 2 unknown numbers are given, whose sum is equal to 76 and the difference is 29. Let's find the two numbers :When we add the two numbers :
X + Y = 76
The difference of two numbers :
X - Y = 29
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 76 X - Y = 29 2X = 105 |
Let's divide 105 to 2 for the first number "X" .
X/2 = 52.5
First number is 52.5
X + Y = 76
So ;
52.5 + Y = 76
Y = 76 - 52.5
Y = 23.5
Second number is 23.5
Question & Answer
The Sum Of Two Numbers Is 76 And Their Difference Is 29 : 52.5 And 23.5
