It's not entirely clear what the original equation is. Please use parenthesis to indicate what is being divided.


--------------------------------------------------


If the equation is a%2B3%2Fb+=+c, then we subtract 3/b from both sides to get


a%2B3%2Fb+=+c


a%2B3%2Fb-3%2Fb+=+c-3%2Fb


a+=+c-3%2Fb


--------------------------------------------------


OR


If the equation is %28a%2B3%29%2Fb+=+c, then we multiply both sides by 'b' first. Then we subtract 3 from both sides


%28a%2B3%29%2Fb+=+c


%28%28a%2B3%29%2Fb%29%2Ab+=+c%2Ab


a%2B3+=+bc


a%2B3-3+=+bc-3


a+=+bc-3

this depends very much on whether you meant:

a + 3/b = c

or you meant:

(a + 3) / b = c

in the first case, you would solve it as follows:

start with:

a + 3/b = c

subtract 3/b from both sides of the equation to get:

a = c - 3/b

in the second case, you would solve it as follows:

start with:

(a + 3) / b = c

multiply both sides by 3 to get:

a + 3 = c * b

subtract 3 from both sides of the equation to get:

a = c * b - 3
