Question

If four times a number, added to 3 is divided by the number plus 2, the result is seven halves. Find the number.

The number is…

Answer 1

X=-8

Explanation:

A number x is multiplied by 4, added to 3, and then divided by x+2, leaving us with 7/2. Or, as an equation:

`(4x + 3)/(x + 2) = (7)/(2)`

Now, let's cross multiply:

`2(4x + 3) = 7(x + 2)`

`8x + 6 = 7x + 14`

And solve:

`x + 6 = 14`

`x = - 8`
