If the difference of a number & four is doubled, the result is 1/4 less tha the number. ??

Answer 1

[06]
Let the number be x
According to the condition of the problem,
2(x-4)=x-1/4
Multiplying both sides by 4
8(x-4)=4(x-1/4)
8x-32=4x-1
8x-4x= -1+32
4x=31
x=31/4= 7 3/4

Answer 2

Set up an equation to solve this first:
difference of x and 4=x-4
doubled= 2(x-4)
set it equal to 1/4 less than the number
2(x-4)=x-1/4
solve for x:
2x-8=x-1/4
x=8-1/4
x=31/4

Answer 3

Let the number be x
From the question,

2(x - 4) = x - (1/4)
2x - 8 = x - (1/4)
x = 8 - (1/4)
x = 31/4

the number is 31/4
