Answer 1

1)

$8 - 6x = x - 6$

$8 + 6 = x + 6x$

$14 = 7x$

$x = \frac{14}{7}$

$x = 2$

2)

$- 9m - 12 = 15$

$- 12 - 15 = 9m$

$- 27 = 9m$

$- \frac{27}{9} = m$

$- 3 = m$

3)

$\frac{x}{6} - 7 = - 10$

$\frac{x - 42}{6} = - 10$

$x - 42 = - 60$

$x = 42 - 60$

$x = - 18$

4)

$\frac{x}{2} - 5 = \frac{x}{9} + \frac{x}{3}$

$\frac{x - 10}{2} = \frac{3x + 9x}{27}$

$27(x - 10) = 2(3x + 9x)$

$27x - 270 = 24x$

$27x - 24x = 270$

$3x = 270$

$x = \frac{270}{3}$

$x = 90$

5)

$- 3 + 3x + 10 - 5x = x + 12 - 4x + 15$

$7 - 2x = 27 - 3x$

$3x - 2x = 27 - 7$

$x = 20$
