Solve this problem by writing and solving an inequality. 7 more than four times a number is less than -40.

I need to find a number that when multiplied by 4 and then adding 7 is less than -40. Let's call the number "x".
The inequality would be:
4x + 7 < -40
To solve this, I will subtract 7 from both sides of the inequality:
4x < -40 - 7
4x < -47
Finally, I will divide both sides of the inequality by 4:
x < -47/4
So, the number "x" is less than -47/4.
