Question

One-eighth a number is two more than one-fourth the number. What is the number? A. −16 B. −4 C. 8 D. 16

Answer 1

A. -16.

Explanation:

1/8 x = 1/4 x + 2 where x is the number to be found.

Subtract 1/4 x for both sides of the equation:

-1/8x = 2

x = 2*-8

x = -16

Answer 2

`\mathrm{A}`

Explanation:

Let that number be x.

`1/8x=2+1/4x`

`1/8x-1/4x=2`

`-1/8x=2`

`x=2 * -8/1`

`x=-16`
