Solve the system of equations by susituition. What is the solutions for x? 2x + y = 1
4x + 2y = -1

A: x = 0
B: x = 2
C: There is no x value, as there is no solution.
D: x can be any value, as there is an infinite number of solutions.

a

step-by-step explanation:

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.
