Question

the sum of two number is 35 and the difference is 7 then find the numbers

Answer 1

let one of the number be x

the other no = x+7

given, x+7 + x = 35

2x + 7 = 35

2x= 35 - 7

2x= 28

x = 28÷ 2

x= 14

x=14

x+7= 14+7 = 21

no. are 14 and 21

Answer 2

Let one of the number be x

And the other number be 35 - x

According to the given condition

x - (35 - x) = 7

☞ x - 35 + x = 7

☞ 2x - 35 = 7

☞ 2x = 7 + 35

☞ 2x = 42

☞ x = 21

∴ One number ☞ x

☞ 21

∴ Other number ☞ 35 - x

☞ 35 - 21

☞ 14
