Answer 1

Does the problem look like this?

2n - \(\rm \large \frac{7}{3}\) = 15?

Answer 2

Or \(\rm \large \frac{2n~-~7}{3}\) = 15

Answer 3

I will chose my second choice =) Either way they end up being the same answer.

Answer 4

So first you must multiply the 3 on both sides of the equation

\(\rm \large \frac{2n~-~7}{3} * 3\) = 15 * 3
2n - 7 = 15 * 3

So what is 15*3?

BATMAN!!

Answer 14

OKAAAY well since he is not responding 15 * 3 = 45, so now we plug is 45 were 15 * 3 was.

2n - 7 = 45

Next we have to add 7 on both sides, since we are subtracting 7 in the original problem

2n - 7 + 7 = 45 + 7

2n = 45 + 7

Answer 15

So what is 45 + 7

Answer 16

Why thank you, Batman

Answer 17

52

Answer 18

Yes~ Now we plug in 52 where 45 + 7 was

2n = 52

Answer 19

Do you know what we do nex?

Answer 20

no what do we do :D

Answer 21

We multiply 2 on both sides

So what is 52 x 2?

Answer 22

104

Answer 23

Yes so n = 104

Answer 24

yay
