$-(2-3x)+x=9-x$
Hint (a):
Simplify the equation as much as possible, then solve for $x$ .
Answer (a):
$x=2.2$

$\frac{6}{x+2}=\frac{3}{4}$

Hint (b):
Isolate the $6$ by multiplying both sides of the equation by the denominator, $x + 2$ .
Answer (b):
$6$

$5 - 2 ( x + 6 ) = 14$

Hint (c):
Refer to part (b).
