Solve the system by elimination.
6x + 5y = 4
18x – 4y = 88
The solution set is {|
(Simplify your answer. Type an ordered pair.)

(4,-4)

Step-by-step explanation:

3*(6x+5y=4)

18x+15y=12

-) 18x – 4y = 88

19y = -76

y=-4

plug back into first equation

6x + 5(-4) = 4

6x = 4+20

x=4

26

step-by-step explanation:

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
