Question
--------------------------------------------------------------------------------
$\frac{2}{3}x - \frac{1}{2} = x + \frac{7}{6}$

--------------------------------------------------------------------------------
Rewrite the right to the left
--------------------------------------------------------------------------------
$x + \frac{7}{6} = \frac{2}{3}x - \frac{1}{2}$

--------------------------------------------------------------------------------
Take away 2/3x from both sides
--------------------------------------------------------------------------------
$x + \frac{7}{6} - \frac{2}{3}x= \frac{2}{3}x - \frac{1}{2} - \frac{2}{3}x$
$x - \frac{2}{3}x + \frac{7}{6}= \frac{2}{3}x - \frac{2}{3}x - \frac{1}{2}$
$\frac{7}{6} + \frac{1}{3}x= - \frac{1}{2}$

--------------------------------------------------------------------------------
Take away 7/6 from both sides
--------------------------------------------------------------------------------
$\frac{7}{6} + \frac{1}{3}x - \frac{7}{6} = - \frac{1}{2} - \frac{7}{6} 
$
$\frac{7}{6} - \frac{7}{6} + \frac{1}{3}x = - \frac{1}{2} - \frac{7}{6}$
$\frac{1}{3}x = - \frac{1}{2} - \frac{7}{6}$

--------------------------------------------------------------------------------
Change the denominator to be the same and minus
--------------------------------------------------------------------------------
$\frac{1}{3}x = - \frac{3}{6} - \frac{7}{6}$
$\frac{1}{3}x = - \frac{10}{6}$

--------------------------------------------------------------------------------
Multiply by 6 on both sides
--------------------------------------------------------------------------------
2x= -10

--------------------------------------------------------------------------------
Divide by 2 both sides
--------------------------------------------------------------------------------
x = -5

--------------------------------------------------------------------------------
Answer : x = -5

Answer from: Quest

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

Answer from: Quest

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
