Question

if 1/4 of the sum of a number and 7 is 4 less than 3 times the number find the number

Answer 1

let the number be x
so, A. T. q, 1/4(x+7)=3x-4
=>x/4+7/4=3x-4
=>x+7/4=3x-4
=>x+7=4(3x-4)
=>x+7=12x-16
=>x-12x=-7-16
=>-11x=-23
=>x=23/11
so, the answer is 23/11

Answer 2

Number  = a

1/4 x (a + 7) =( 3 x a) - 4     (given)

a + 7 = 12a - 16

11a = 23

a = 23/11
