Solve: 3x + 2y = 11 and 6x - 2y = 25.

x = 4, y = -0.5

or (4,-0.5)

Step-by-step explanation:

Given:

Solution:

Adding equations (i) and (ii):

==> (3x + 2y) + (6x - 2y) = 11 + 25

2y gets cancelled:

==> 9x = 36

dividing the equation by 4:

==> x = 4

Substituting 4 for x in equation (i):

==> 3(4) + 2y = 11

==> 12 + 2y = 11

subtracting 12 from both sides:

==> 2y = 11 - 12

==> 2y = -1

dividing both sides by 2:

==> y = -1/2

==> y = -0.5

4 + 5 7/9= 9 7/9

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
