Question

What are those two number whose sum is 58 and difference is 28??​

Answer 1

Answer:

43 and 15.

Step-by-step explanation:

Lets take the two number as x and y.

x + y = 58 and x - y = 28

Adding the above two equations,

x + y + x - y = 58 + 28

Cancel the -y and +y as they equal 0.

2x = 86

Divide 86 by 2 to cancel two from 2x in LHS,

x = 43

Putting the value of x in x + y = 58,

43 + y = 58

y = 58 - 43 = 15

Therefore the two numbers are 43 and 15.
