Approach to solve ceiling identities

25 Views Asked by At

Other than trial and error, is there a way to solve the following problem

Show that the smallest integer value of $N$ for which

$$\left\lceil\frac{N}{4}\right\rceil = 7$$ is 25

I am not able to find a way to proceed given the identities I know like: $$\left\lceil\ -x \right\rceil = -\left\lfloor\ x\right\rfloor$$ and $$\left\lceil\ x + n \right\rceil = \left\lceil\ x\right\rceil + n$$
