5-50.

Solve each of the following equations. Homework Help ✎

1. $\frac { 3 x } { 5 } = \frac { x - 2 } { 4 }$

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

3. $\frac { 2 x } { 5 } - \frac { 1 } { 3 } = \frac { 137 } { 3 }$

4. $\frac { 4 x - 1 } { x + 1 } = x - 1$

$x = -\frac{10}{7}$

4x − 1 = 3x2

0 = 3x2 − 4x + 1

Multiply each term by the common denominator of 3 and 5.

x = 115

Use the same method as in part (b).
