Start by writing down "p" to be potatoes, set that equal to something like this:

p=

now the "four more" part means addition, so on the other side of the equation write:

p=4+

now for the "half the number of green beans" means division by two (or multiplication by 1/2)

p=4+g/2 OR p=4+1/2 (g)

now convert the equation to be in terms of g by subtracting 4 from both sides and multiplying both sides by 2 (or dividing by 1/2)

g=2 (4-p) or g = (4-p) / (1/2)
