2a + ca – b = 5
solve for a

Solution for 2a-b=5 equation:

Simplifying

2a + -1b = 5

Solving

2a + -1b = 5

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add 'b' to each side of the equation.

2a + -1b + b = 5 + b

Combine like terms: -1b + b = 0

2a + 0 = 5 + b

2a = 5 + b

Divide each side by '2'. and you get 0.5

a(2+c)-b=5

a(2+c)=(5+b)

a=(5+b)/(2+c)

worked it out i believe

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
