Question

19/2x + 3/5 = 13/2x

Answer 1

The X's confuse me

Answer 2

multiply both sides by 10x

Answer 3

95x+6=65x?

Answer 4

x=-1/5

Answer 5

\[\frac{19}{2x}+\frac{3}{5}= \frac{13}{2x}\]

let's look at 10x times 19/2x:
\[10x \cdot \frac{19}{2x}= \frac{10\cancel{x}19}{2\cancel{x}}=5\cdot 19= 95\]

Answer 6

do you see that the x's cancel except for 10x * (3/5) ?

Answer 7

Oh! Yes i see that :)

Answer 8

So instead of
95x+6=65x?

you should get
95 +6x= 65 right?

Answer 9

-5?

Answer 10

yes.

Answer 11

we multiplied everything by 10x to get rid of the x's in the denominator. It is a good trick to remember.
