Question

x divided by -4 is 13. What is x???

Answer 1

x divided BY -4 IS 13
is means equal
divided by means x/n
so

x/-4 = 13
Multiply by the reciprocal of 1/-4 which is -4/1 to both sides
x = 13 x -4
x = -52

Answer 2

\(\displaystyle \frac{x}{-4}=13\)

To get rid of the negative 4 you need to multiply each side by -4.

\(\displaystyle (\frac{-4}{1})(\frac{x}{-4})=13(-4)\)

\(\displaystyle (\frac{\cancel{-4}}{1})(\frac{x}{\cancel{-4}})=13(-4)\)

\(\displaystyle \frac{x}{1}=13\times-4=~?\)
