10-72.

Solve the following equations for $x$, if possible. Check your solutions.

1.  $-(2-3x)+x=9-x$

Simplify the equation as much as possible, then solve for $x$.

$x=2.2$

1.  $\frac{6}{x+2}=\frac{3}{4}$

• Isolate the $6$ by multiplying both sides of the equation by the denominator, $x + 2$.

$6$

1.  $5 - 2 ( x + 6 ) = 14$

• Refer to part (b).

1.  $\frac{1}{2}x−4+1=−3−\ \frac{1}{2}x$
