2/9v+4−2/3v=5

Answer 1

\[\frac{ 2 }{ 9 }v + 4 - \frac{ 2 }{ 3 }v = 5\]

Answer 2

Do you know what the first step would be?

Answer 3

combine like terms

Answer 4

Correct, so how would we do that with these fractions?

Answer 5

\[\frac{ 2 }{ 9 }-\frac{ 2 }{ 3 }\]

Answer 6

Yes, but in order to add/subtract with fractions, what is required?

Answer 7

least common denominators which is 9

Answer 8

Yes, so how would we get 2/3 to fulfill that requirement?

Answer 9

\[\frac{ 6 }{ 9 }\]

Answer 10

Remember,
\[-\frac{ 2 }{ 3 } \times \frac{ 3 }{ 3 } = - \frac{ 6 }{ 9 }\]

Answer 11

Negative

Answer 12

So we have \[\frac{ 2 }{ 9 }v + 4 - \frac{ 6 }{ 9 }v = 5\]

Answer 13

What now?

Answer 14

subtract the two fractions

Answer 15

What do you get?

Answer 16

\[\frac{ -8 }{ 9? }\]

Answer 17

positive 8

Answer 18

\[\frac{ 2 }{ 9 }v - \frac{ 6 }{ 9 }v\]

Answer 19

\[\frac{ -4 }{ 9 }\]

Answer 20

Yep

\[-\frac{ 4 }{ 9 }v\]

So we have,

\[-\frac{ 4 }{ 9 }v + 4 = 5\]

Answer 21

so now we subtrac the 4 on both sides

Answer 22

Yes,

We get..

\[-\frac{ 4 }{ 9 }v = 1\]

Answer 23

v=-4/9

Answer 24

Wait...

Answer 25

You multiply both sides by -9, you get 4v = -9, then divide by 4

Answer 26

\[v = -\frac{ 9 }{ 4 }\]

Answer 27

2 1/4

Answer 28

Keep it in the earlier form unless your teacher wants it in that form

Answer 29

Mixed fractions are kind of informal and used usually in just elementary school
