Question

100 equals 15 minus x divided by 5

Answer 1

The answer is -485.

To find this we first need to get rid of the 5 in the denominator.

100 =
`(15 - x)/(5)`

So we multiply each side by 5.

500 = 15 - x

Now we need to get rid of the 15. So we subtract 15 from both sides.

485 = -x

Then since our x is negative, we need to divide by -1.

-485 = x
