Question

solve the rational equation 3x/4 = 5x + 1/3???

Answer 1

\[\frac{3x}{4}=\frac{5x+1}{3}\]?

Answer 2

Do I begin by multiplying 3 to 3x and 4 to 5x + 1? would it become 9x/12x = 20x + 4/12

Answer 3

yes, you "cross multiply" and get
\[3\times 3x=4(5x+1)\]

Answer 4

so then its 9x = 20x + 1? and wat do i do after?

Answer 5

don't forget the distributive law !!

Answer 6

wait, what would it be then?

Answer 7

\[9x=20x+4\]

Answer 8

oh yeah! ok. so then i subtract 4 or divide by 9?

Answer 9

probably subtract \(20x\) from both sides
then divide by \(-11\)

Answer 10

r u sure?

Answer 11

pretty sure, yes

Answer 12

\[9x=20x+4\]
\[-11x=4\]
\[x=-\frac{4}{11}\]
