Best Answer
Hint: Try to translate the question from English into Mathematics. (I'll do everything in cents)
$$400=5x+10y$$
I got this from "You spend $\$4.00$" and "$\$0.05$ to send a text message and $\$0.10$ to send a picture". Also, we have
$$x=y+5$$
This is from "$5$ more text messages than pictures".
So, with this information, can you solve it?
