Hi,
For this question, we first add 4 to both sides of the equation to get:
x / 3 = 13
Next, multiply both sides by 3 in order to isolate for x alone. We will therefore get:
FINAL ANSWER: x = 39
I hope that helps you out! Please let me know if you have any other questions!
Sincerely,
Andrew

this is of the type..
a -b =c..
so if you are subracting b from a, then doing the opposite to both sides to isolate a, which is where the variable is, we get
a-b +b=c +b.. now lets apply that to your problem..
x/3 - 4=9..
add opposite to both sides..
x/3 -4 +4 =9+4.. simplifying
we get
x/3 +0 =13
we don't actually have to write the zero, here I wrote it to let you know that when you add two opposite numbers the result is always zero..
finally we get x/3=13.. this says a number divided by 3 is 13..
to find the answer to that, we again do the opposite of operation.. and that would be multiplication.. so that
(x/3)*3 =13*3..
on the left you get x on the right you get 39..
so here is the final answer x=39.. fully explained, now you don't have to write everything I did all the time, but read it so you can know what to do next time.. hope that explains why we do what we do..

x / 3 - 4 = 9
x / 3 = 9 + 4
x / 3 = 13
x = 13 x 3
x = 39

Since u r dividing 3 with the x, u have to multiply 3 with both sides.
1) x / 3 - 4 = 9
2) (x / 3 - 4 ) + 4 = 3 ( +4)~~~~~~~~~~~~~~`add both sides with 4
3) x /3 = 7 ~~~~~~~~`~~~~~~~~next multiply 3 to each side
4) 3 (x/3) = 7
5) x = 39
the answer is 39
i hope that helped!
