Question

Sum of the two numbers is 51. If one of the numbers exceed the other number by 11, then find​

Answer 1

Answer:

sum of both no.= 51 let the first no. be x

the second no. = x+11

sum= x+x+11= 51

2x+11=51

2x=51-11

2x=40

x= 40/2

x= 20

so, the first no. is 20 and the second no. is 31.

Answer 2

Step-by-step explanation:

let 'x' and 'y' be a two number.

According to the question

x+y = 51.........(1)

also first number is exceed the other number by 11

x= y+11.........(2)

using equation (2) in equation (1)

( y+11) + y = 51

2y +11 =51

2y = 51 -11

2y = 40

y = 40/2

y =20
