Question

Write an equation for the following:

If one-sixth of a number $x$ is subtracted from nine times the number, the result is $312$.

Answer 1

If one-sixth of a number $x$ is $\frac{1}{6}x$ and nine times the number $x$ is $9x$.

Now, when we subtract $\frac{1}{6}x$ from $9x$ we get $9x-\frac{1}{6}x$.

Now, equating it with $312$ we get our result.

Hence, the required equation is $9x-\frac{1}{6}x=312$
