The Sum Of Two Numbers Is 75 And Their Difference Is 29
The problem given says that 2 unknown numbers are given, whose sum is equal to 75 and the difference is 29. Let's find the two numbers :When we add the two numbers :
X + Y = 75
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 = 75 X - Y = 29 2X = 104 |
Let's divide 104 to 2 for the first number "X" .
X/2 = 52
First number is 52
X + Y = 75
So ;
52 + Y = 75
Y = 75 - 52
Y = 23
Second number is 23
