Question

)The sum of two numbers is 40. Taking the numbers as x and y from an equation b)Their difference is 10 . Using this idea from another equation c)Find the numbers​

Answer 1

Suppose two numbers are x and y

Hence,

x + y = 40…… {1}

x - y = 10……….{2}

Add eqiation 1 and 2,

2x = 50.

x = 25.

Put these value in equation 1,

25 + y = 40

y = 15.

Hence,. x = 25. y = 15

Answer 2

Given: The Sum of two numbers is 40. & The difference of these two numbers is 10.

Need to find: The numbers?
