Answer:
Take 66 and subtract 10 to get 56
Divide 56 by 2 to get 28 - this is the first number.
Add 10 to 28 to get 38 - this is the second number.
Prove by adding 28 + 38 to get 66
The two numbers are 28 and 38 whose sum is 66 and the difference is 10.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
Let the two numbers be x and y respectively. From the question, we will make the following expression:-
x + y = 66
x - y = 10
By solving the above two linear equations add both the equations.
x + y + x - y = 66 + 10
2x = 76
x = 38
Now put the value of x in any one equation above:-
x - y = 10
38 - y = 10
y = 38 - 10
y = 28
Therefore two numbers are 28 and 38 whose sum is 66 and the difference is 10.
