Question

. Find two numbers such that one is more than the other by 21 and their sum is 91.
​

Answer 1

LET

X AND Y be the two numbers...

by given data ...

X - Y = 21--------------EQUATION 1

X + Y= 91--------------EQUATION 2

ADD 1 + 2

WE GET

2X = 112

X = 56 --------- ANSWER 1

SUBTITUTE VALUE OF X IN EQUATION 1

56 - Y = 21

Y = 56 - 21

Y = 35 ----------------- ANSWER 2

Answer 2

the numbers are 56 and 35

Step-by-step explanation:

let let one number be x

other number = x+21

therefore,

X+X+21=91

2X=70

X=35

the other number is (X+21)=35+21=56
