How do i solve this ons

x=1, y=−4

Step-by-step explanation:

Divide each term by −2 and simplify.

x=−7y/2−13

7x+5y=−13

Replace all occurrences of x with −7y/2−13 in each equation.

−39y/2−91=−13

x=−7y/2−13

Solve for y in the first equation.

y=−4

x=−7y/2−13

Replace all occurrences of y with −4 in each equation.

x=1

y=−4

answer: i'm not sure

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.
