Hello.

First, let the number be r.

5 times r is written like this:


\rm{5r}

Now, add 45:


\mathrm{5r+45}

Now, the sum of 5r+45 is equal to the sum of 85 and 140:


\mathrm{5r+45=85+140}

In order to solve this equation, we need to add 85 and 140:


\mathrm{5r+45=225}

Now, subtract 45 from both sides:


\mathrm{5r+45-45=225-45}


\mathrm{5r=225-45}


\mathrm{5r=180}

The last step is to divide both sides by 5:


\mathrm{r=36}

Therefore, the answer is


\rm{r=36}

I hope it helps.

Have a nice day.
