11-60.

Solve each equation below for x.

$1234x + 23456 = 987654$
Answer (a):
$x\approx781.36$

$\frac { 10 } { x } + \frac { 20 } { x } = 5$
Hint (b):
Multiply both sides of the equation by $x$ .

$5x^2 − 6x + 1 = 0$
Hint (c):
Factor and use the Zero Product Property.

$x^3- 3x^2 + 2x = 0$
Hint (d):
$x$ is a common factor. How many solutions do you expect from a cubic equation?
