Commment and tell me if u need more help
Answer:
p=2(L+W)
p=304
L=40+w
p=2(40+w+w) ,40+w is the value of L
304=2(40+2w)
304/2=2(40+2w)/2 divided both side by 2
152=40+2w
152-40=2w
112=2w
112/2=2w/2
w=56
and L =40+w
40+56=96.
so L=96 and W=56.

C) isolating a variable in one of the equations.
<u><em>Explanation</em></u><span><u><em>: </em></u>
In order to solve a system of equations using substitution, we must have one of the variables isolated; this is the only way we have something to substitute. If one of the variables is not already isolated, that must be our first step.</span></span>
You should do 6821 × 2 and then your answer divide it by 6821
2/12 = 1/6
1×2=2 and 6×2=12
1/4=2/8
1×2=2 and 4×2=8
