Question

difference between two number is 30 twice the greater number is less than 7 times smaller by 5 find the number and solve the equation​

Answer 1

let the numbers be x and y

x-y= 30....(1)

now,

2x= 7y+5

2x-7y= 5....(2)

multiplying eq (1) by 2

2x-2y= 60....(3)

subtracting (2) from (3),

2x-2y= 60

- 2x+ 7y= -5

5y= 55

therefore, y= 55/5= 11

substituting value of y in (1),

x-y= 30

x-11= 30

x= 30+11

x= 41.

therefore,

value of x= 41, y= 11
