Which of the following is a strong introductory sentence?

a-to kill you or not to carry, that is the question.
b-i don’t agree with any open carry laws.
c- should each of the united states allow citizens to openly carry a weapon
d-this essay will explain the open carry laws of united states

I wouldn’t choose any of these my self but, D would seem like the strongest way to go, you shouldn’t use A/B in the introductory sentence, it seems better if it was in a body paragraph, you shouldn’t use C because you don’t wanna ask a question in your essay, so D would be the best way to go ☺️, Hope that helps

This essay will explain the open carry laws of United States

Ican’t answer if you don’t give me the excerpt

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4

answer: x = 4 and y = 4
