Question

Equations with fractions; Show work
15m + 3/2 = -6

Answer 1

I know I would multiply both sides by 2 right?

Answer 2

You have to multiply EACH TERM on both sides by 2

Answer 3

Then would I subtract 3 from both sides or is there something I have to do before that!

Answer 4

correct you have to subtract 3 from both sides

Answer 5

15m + 3/2 = -6
15m = -15/2
m = -1/2

Answer 6

If you are unafraid of fractions. :D

Answer 7

That is not what I got! I got
15m + 3 = -12
15m + 3 -3 = -12 - 3
15m/15 = -15/15
m= -1
Is that wrong!

Answer 8

Hmmm, I have gotten 3 different answers now!

Answer 9

15m + 3/2 = -6
30m+3 = -12
30m = -15
m = -1/2

Two different ways, same answer.

Answer 10

15m + 3/2 = -6
2(15m + 3/2) = 2(-6)
30m + 3 = -12
30m = -12-3
m = -15/30
m = -1/2

THIS IS THE RIGHT ANSWER!!!

Answer 11

As well, I verified with my calculator. And if you plug it back in, it works.

Answer 12

skullpatrol started with the wrong initial equation!!!

Answer 13

You guys do know that 15m + 3 is over 2 right! Not 3/2. I someone put it as 3/2.

Answer 14

Then you should have written it as (15m+3)/2...

Answer 15

\[\frac{15m+3}{2} = -6\]
USE PROPER FORMAT!!!
That is the single most aggravating thing you can do.....

Answer 16

(15m+3)/2 = -6
15m + 3 = -12
15m = -15
m = -1

Answer 17

(15m + 3)/2 = -6
2(15m + 3)/2 = 2(-6)
15m + 3 = -12
15m = -12-3
m = -15/15
m = -1

Answer 18

This illustrates EXACTLY why you should use proper format whilst you are asking and answering a question. It clears up confusion and expedites assistance to the asker.
