Question

Solve for w in P = 2 w + 2 l ,P = 38 and l= 12

Answer 1

So basically: 38=2*W +2*12

Answer 2

ummm is it not that you need to find w?
then move the equation around to find w

Answer 3

kay.

Answer 4

How do I do that?

Answer 5

I'm not very good at doing that...

Answer 6

well you have 38=2w+24
so move the 24 to the left by eliminating it on the right by -24 meaning also reducing -24 from the left
=>
so 38-24=2w+24-24
that is 14=2w
now divide both by two to obtain a 1 before w since 2/2=1 and 1w=w
so 14/2=2/2w=w => w=7
