write as a 7th grader

solve it

Answer 1

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.
