Question

Solve for m:

Answer 1

what happens to the equation when you multiply both sides by 2 ?

Answer 2

and please write down the result

Answer 3

30m+6=-12

Answer 4

why did you multiply hte left side by 4?

Answer 5

You said multiply both sides by 2

Answer 6

yes, but what you have written

you multiplied the right side by 2
and you multiplied the left side by 4, not 2

Answer 7

15x2=30

Answer 8

\[\frac{15m+3}{2} = -6\]

multiplying both sides by 2

\[\frac{2}{1}\frac{15m+3}{2} = -6 * 2\]

\[\frac{2}{2} =1\]

\[15m +3 = -12\]

Answer 9

15 x 2 is 30
but you cant ignore the 2 in the denominator

Answer 10

ohhh I see now

Answer 11

ok, now since you're solving for m, you want to isolate the m term

this means you want to move the 3 to the right side

what would you have to do to BOTH!!! sides in order to remove the 3 on the left side?

Answer 12

subtract 3

Answer 13

ok, and what would you get when you subtract 3 from both sides of the equation?

Answer 14

15m=-15

Answer 15

good

Answer 16

now, again the goal is to isolate m so its alone on one side


this means we need to remove the 15 thats on the left side

any ideas what you would have to do to both sides of the equation to get rid of the 15?

Answer 17

divide m= -1

Answer 18

divide both sides by 15
and yes m=-1 is the answer

good job

Answer 19

i suggest closing this question and writing another one
