The Sum Of Two Numbers Is 85 And Their Difference Is 29
The problem given says that 2 unknown numbers are given, whose sum is equal to 85 and the difference is 29. Let's find the two numbers :When we add the two numbers :
X + Y = 85
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 = 85 X - Y = 29 2X = 114 |
Let's divide 114 to 2 for the first number "X" .
X/2 = 57
First number is 57
X + Y = 85
So ;
57 + Y = 85
Y = 85 - 57
Y = 28
Second number is 28
