Which ordered pair (x, y) is a solution to given system of linear equations? (3x+y = 1
15x+y = 3
O (-2, 1)
O (-0.5, 0.5)
0 (0.5, -0.5)
O (1, -2)

or

Step-by-step explanation:

Given

Required

Determine the solution

We'll solve using elimination method.

Subtract the first equation from the second:

Make x the subject:

Substitute for x in the first equation

Make y the subject

Hence, the solution is:

or

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
