Question

What is x-4/3=3x+4/7 what is x expain how you got the answer

Answer 1

X-4/3 = 3x-4/7
First add 4/3 to each side -->x = 3x + 16/21
Then Subract 3x from each side -->-2x = 16/21
Then divide each side by -2 --->x = -3.81

Answer 2

$x- \frac{4}{3} = 3x+ \frac{4}{7}$
You want to put like terms on like sides. 
$x-3x = \frac{4}{3}+ \frac{4}{7}$

Then on the right side use common denominator of 21:
$-2x= \frac{28}{21}+ \frac{12}{21}$

$-2x = \frac{40}{21}$
Then divide by -2 and get:
$x = \frac{40}{21*-2} = \frac{-20}{21} = -.9524$
