Answer:
2y-7=5
Explanation:
since the number represents y
the product of 2 and a number would be 2y
then since it says seven less than that you subtract 7 from 2y
this gives you 2y-7
finally, it says its equal to 5
so then all you have to put is 2y-7=5 as your answer since it only asks you to make the equation based off the sentence, not solve it.
