Can someone pls help

* Substation :

Subtract y from both sides of the equation.

x=6−y

x−y=4

Replace all occurrences of x with 6−y in each equation.

6−2y=4

x=6−y

Solve for y in the first equation.

y=1

x=6−y

Replace all occurrences of y with 1 in each equation.

x=5

y=1

The solution to the system is the complete set of ordered pairs that are valid solutions. (5,1)

The result can be shown in multiple forms. Point Form: (5,1)

Equation Form: x=5,y=1

* Elimination :

Multiply each equation by the value that makes the coefficients of x opposite.

       x+y=6

(−1)⋅(x−y)=(−1)(4)

Simplify.

 x+y=6

−x+y=−4

Add the two equations together to eliminate x from the system.

   (x+y=6) + (−x+y=−4) = (2y=2)

Divide each term by 2 and simplify.

y=1

Substitute the value found for y into one of the original equations, then solve for x.

x=5

The solution to the independent system of equations can be represented as a point.

(5,1)

The result can be shown in multiple forms. Point Form:(5,1)

Equation Form: x=5,y=1

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.
