12-6.

Solve the following equations for $x$ .

$4x-6y=20$
Hint (a):
Add $6y$ to both sides and solve for $x$ .
Answer (a):
$x = 5 + 1.5y$

$\frac{1}{2}\left(x-6\right)=9$
Hint (b):
Multiply both sides by $2$ first.

$\frac { 4 } { 3 x } + \frac { 6 } { x } = 9$
Step (c):
$4 + 18 = 27 x$

$3+\sqrt{5-x}=5$
Hint (d):
Subtract $3$ from both sides and then square both sides to remove the square root. Solve for $x$ .
