Answer 1

Explicación paso a paso:

1)

$4x - 3 = 2x + 1$

$4x - 2x = 1 + 3$

$2x = 4$

$x = 4 \div 2$

$x = 4$

2)

$4(2 - x) + 1 = - 2x$

$- 4x + 9 = - 2x$

$9= 4x - 2x$

$9= 2x$

$x = \frac{9}{2}$

3)

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

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

$- \frac{17}{4} = \frac{2}{3} x$

$x = - \frac{17}{4} \div \frac{2}{3}$

$x = - \frac{51}{8}$
