Answer:
5x-7 has to equal to something smaller than 13
5x-7=5
Answer: x < 4
Step-by-step explanation:
Disregarding the lesser than sign, we can treat this equation as 5x-7=13. This doesn't work all the time as there are rules, but those rules don't apply to a simple inequality such as this.
5x-7<13
5x<20
x<4
And so, our answer is x<4
