3(x-2)+7=19 I’m sorry can some one please help me I just don’t get it

x=6

Step-by-step explanation:

3(x-2)+7=19

distribute the 3 through the parentheses:

3x-6+7=19

Simplify:

3x+1=19

Move the constant (1) to the right-hand side and change its sign

3x=19-1

Subtract the numbers:

3x=18

Divide both sides by 3 to get x alone:

x=6

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
