Question

what does it mean to solve the equation for M then find the value of M in each N

Answer 1

do you have an example to go by?

Answer 2

yes hold on

Answer 3

\[M+3n=7n\]

Answer 4

\[-2,0,1\]

Answer 5

that is the end of it

Answer 6

solve for M means "get M alone on one side" of the equal sign

Answer 7

i know that part i ment the part about the N

Answer 8

what do you get when you solve for M in this:
M+3n=7n

Answer 9

ok so to solve for M in M+3n=7n
you have to leave M by itself M=7n-3n
then once you have M by itself you can plug in what you got for M then solve
7n-3n+3n=7n
everything cancels out therefore it means that it is exact opposite

Answer 10

do you understand what i tried to say? if not let me know

Answer 11

huh

Answer 12

when u solve for m you have 7n-3n right?

Answer 13

yes

Answer 14

then it ends up being M=10 right

Answer 15

ok now plug in what you got for M
you end up with 7n-3n+3n=7n

Answer 16

how did u get 10?

Answer 17

i divdied 10 from each side

Answer 18

never mind that the wrong prblem

Answer 19

ugh i suck at this

Answer 21

@mathmate

Answer 22

Is it n= -2, 0, 1?

Answer 23

yes

Answer 24

\(M+3n=7n\)

Subtract 3n on both sides.

What would you get?

Answer 25

with the M or with the 3 and 7
