Good explanation Zac but 2-5=-3  not -7 so it is not going to be quite right.    

 

Doesn't really matter - your explanation of how to go about finding the answer is very good :)

2 - (7x + 5) = 13 - 3x.......Expand the brackets

 

2 - 7x - 5 = 13 -3x..........Group like terms

 

-7x - 3 = -3x + 13

 

-16 = 4x........................Divide both sides by 4

 

x = -4

 

(Fixed!  )
