Helll a ii am desprate which equation has solution x = -3? a) 2x - 7 = -1 b) 3x + 8 = 1 c) 1/2x + 8 = 10 d) 1/2 (2x - 6) = -6

Well A.2x-7=-1 equals x=3

And B.3x+8=1 equals x=- 7/8

And C. 1/2x+8=10 equals x=4

And D. 1/2 (2x-6)=-6 equals x=-3

So you’re answer is D. 1/2 (2x-6)=-6

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
