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 = $\frac{15 - x}{5}$

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
