Solve each system of equations by adding, subtracting, or multiplying. 2) x + y = 12 2x + y = 6 show work!

x + y = 12
2x + y = 6

x = 12 -y
2x + y = 6

x = 12 -y
2(12 -y) + y =6

x = 12 -y
24 -2y  + y =6

x = 12 -y
-2y + y = 6 -24 

x = 12 -y
-y = -18

x = 12 - 18
y = 18

x = -6
y=18

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

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
