Question 1047704
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
