Solve by elimination
{10x-4y=-6
{-3x+4y=-1
WORK MUST BE SHOWN

x = -1

y = -1

Step-by-step explanation:

10x - 4y =  -6  (I)

-3x + 4y =  -1 (II)

Add equation (I) & (II) and y will be eliminated.

10x  - 4y = - 6

-3x  + 4y = -1       {Add}

7x           = - 7

         x = -7/7

x = -1

Plugin x =-1 in equation (I)

10*(-1) - 4y = -6

-10 - 4y = -6 {Add 10 to both sides}

     -4y = -6 + 10

     -4y = 4  {Divide both sides by (-4)}

         y = 4/(-4)

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.
