The Sum Of Two Numbers Is 76 And Their Difference Is 10
The problem given says that 2 unknown numbers are given, whose sum is equal to 76 and the difference is 10. Let's find the two numbers :When we add the two numbers :
X + Y = 76
The difference of two numbers :
X - Y = 10
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 76 X - Y = 10 2X = 86 |
Let's divide 86 to 2 for the first number "X" .
X/2 = 43
First number is 43
X + Y = 76
So ;
43 + Y = 76
Y = 76 - 43
Y = 33
Second number is 33
Question & Answer
The Sum Of Two Numbers Is 76 And Their Difference Is 10 : 43 And 33
