Question

simplifying algebra help :x?

Answer 1

Well notice how you already have a common denominator (necessary when adding or subtracting fractions) since you already have that...you can simply write this as

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

can you simplify from here...?

Answer 2

4x^2-9/9 ?

Answer 3

Remember this is adding....4x + x doesn't = 4x²

that would be multiplication....4x * x = 4x²

no look at it like this

\[\frac{ 4x + 1x - 9 }{ 9 }\]

what is 4x + 1x?

Answer 4

5x

Answer 5

Right....so you have

\[\frac{ 5x - 9 }{ 9 }\]

Now I suppose this could still be simplified....so lets do so...by splitting up this fraction

\[\frac{ 5x }{ 9 } - \frac{ 9 }{ 9 }\]

We now 5x/9 cannot be simplified anymore than it is...but what is 9/9?

Answer 6

1?

Answer 7

Right

*keep in mind we COULD have stopped with just

\[\frac{ 5x - 9 }{ 9 }\]

but it could still be simplified....so now we have

\[\frac{ 5x }{ 9 } - 1\]

Answer 8

ah damn hold on i made a mistake when i wrote it >.<
