-4x + 9 y = 9 -x-3y=-6

y = 5

x = 9

Step-by-step explanation:

multiple the second equation by 4 then add both equations up

4×(x -3y = -6 ) ➡ 4x - 12y = -24

4x -12y - 4x +9y = 9 - 24 ➡ -3y = -15

y = 5 use this value to find x

x - 3×5 = -6

33

Step-by-step explanation:

-4x +9y =9- x - 3y= - 6

=33

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
