Answer 4

@TheCalcHater

Answer 5

Ok so you need to isolate the n, the first step is to get rid of the 3 on the left side,
how can you do that?

Answer 6

i think the answer is -18

Answer 7

Well plug it in and check,
what is -2(-18)-2 all divided by 3?

Answer 8

oh bye multiplying 3 i understand how to solvei just want to check

Answer 9

um ok

Answer 10

You're incredibly close with -18 but it's wrong, check your work, might have done a little thing wrong

Answer 11

oh yeah i accidentally wrote 36 rather than 38 so -19

Answer 21

well, one sec
just so you know, it helps if you post each one in their own posting
that way we can all see it

anyway
so, notice 4c + 16 has a common factor of 4
so \(\bf \cfrac{3}{4}(4c+16)=2c+9\implies \cfrac{3(4c+16)}{4}=2c+9
\\ \quad \\
\cfrac{3\cdot {\color{brown}{ \cancel{4}}}(c+4)}{\cancel{4}}=2c+9\)

surely you can do it from there

Answer 22

3*(c+4)=2c+9

Answer 23

yeap
expand and simplify :)

Answer 24

\(\bf \cfrac{3}{4}(4c+16)=2c+9\implies \cfrac{3(4c+16)}{4}=2c+9
\\ \quad \\
\cfrac{3\cdot {\color{brown}{ \cancel{4}}}(c+4)}{\cancel{4}}=2c+9\implies 3(c+4)=2c+9
\\ \quad \\
3c+12=2c+9\implies 3c{\color{blue}{ -2c}}=9{\color{blue}{ -12}}\implies c=?\)

Answer 25

where does 12 come from

Answer 26

@jdoe0001

Answer 27

ur removing 12 from both sides so no change on left but right neds -12
