+2

We have 2 cases, 5+3w2,and53w2

 

Starting with the first case 5+3w2 , we can subtract 5 from both sides to get 3w3, and then divide by 3 for an answer of w1, keeping in mind 3 is positive so we don't switch the sign.

 

Now for our second case, 53w2, we add five to both sides giving us, 3w7, now dividing by 3 and making sure we flip the sign, we get, 

w73

 

But wait, we still have to combine our answers giving us 73w1
