Question

The difference between two number is 7. if the bigger number is multiplied by 3, it becomes 14 less than the number got after multiplying the smaller number by 4. find the original numbers.​

Answer 1

Step-by-step explanation:

let x and y be the requires no

such that x-y=7. EQ 1

where x is greater than y

according to the question

3x= 4y-14 eq 2

from EQ 1

x=7+y

put value of x in EQ 2

3(7+y) = 4y - 14

21-3y = 4y -14

21+14 = 4y +3y

35 = 7y

or y = 35÷ 7

or y = 5

put value of y in EQ 1

x- 5 = 7

or x= 7+5

or x=12
