The length of a rectangle is 4 less than 3 time the width. what is the area of the rectangle?

Use the quations 2L + 2W = Area

and L = 3W -4

Plug the second equation into the first and solve for W

2(3W-4) + 2W = A

6W - 8 + 2W= A

8W - 8 = A

8W = 8

W = 1

Then plug that into the second equation

L = 3(1) -4

L = 3 -4

L = -1

Then plug both of the answers into the first equation

2(-1) + 2(1) = A

-2 + 2 = A

0 = A

That should be the answer, but since there was no given Area, i'm not sure.

I hope this helped though!

i can answer this question sweetie!

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
