Answer 1

$2x + 2 = 3 + x \\ 2x - x = 3 - 2 \\ x = 1$

$3x + 2 = 3 + 2x \\ 3x - 2x = 3 - 2 \\ x = 1$

$10x + 8 = - 6 + 9x \\ 10x - 9x = - 6 - 8 \\ x = - 14$

$21 - 2x = x + 6 \\ 21 - 6 = x + 2 x\\ 15 = 3x \\ 5 = x$

$5x - 3 = - x - 9 \\ 5x + x = - 9 + 3 \\ 6x = - 6 \\ x = - 1$

$- x + 3 = - 2x - 18 \\ - x + 2x = - 18 - 3 \\ x = - 21$

$5x - 20 = 3x - 8 \\ 5x - 3x = - 8 + 20 \\ 2x = 12 \\ x = 6$

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

$4x + 3 = - 3 - 2x \\ 4x + 2x = - 3 - 3 \\ 6x = - 6 \\ x = - 1$

$x - 2 = - 3 + 2x \\ - 2 + 3 = 2x - x \\ 1 = x$

$4x - 5 = - 3 + 6x \\ - 5 + 3 = 6x - 4x \\ 2 = 2x \\ 1 = x$

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