Answer 8

So first off you need to start with parenthesis again. Since you cant do anything with (q+14) you wanna distribute the - which then turn it into -Q-14=-3+(-14) This equation turns into -q-14=-3-14 because if you add a negitive you subtract. Then you want to isolate the variable -q. You don't want the variable to be negative so add Q to the left and right side of the equation and then do the same with -3 and -14 add them to both sides. You will end with 3=q
