Answer 1

$5x - 4 = 21 \\ 5x = 21 + 4 \\ 5x = 25 \\ x = 25 \div 5 \\ x = 5$

$9 - 5x = - 1 \\ - 5x = - 1 - 9 \\ - 5x = - 10 \\ x = - 10 \div 5 \\ x = 2$

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

$3x + 5 = - x - 7 \\ 3x + x = - 7 - 5 \\ 4x = - 12 \\ x = - 12 \div 4 \\ x = - 3$

$6x + 2 = 50 \\ 6x = 50 - 2 \\ 6x = 48 \\ x = 48 \div 6 \\ x = 8$

$3 - 4x = - 5 \\ - 4x = - 5 - 3 \\ - 4x = - 8 \\ x = - 8 \div -4 \\ x = 2$

$9 - 4x = 2x - 3 \\ - 4x - 2x = - 3 - 9 \\ - 6x = - 12 \\ x = - 12 \div - 6 \\ x = 5$

$9x + 8 = - 1 \\ 9x = - 1 - 8 \\ 9x = - 9 \\ x = - 9 \div 9 \\ x = - 1$


$7 - 2x = + 1 \\ - 2x = + 1 - 7 \\ - 2x = - 6 \\ x = - 6 \div - 2 \\ x = 3$

$4x + 7 = 2x - 3 \\ 4x - 2x = - 3 - 7 \\ 2x = - 10 \\ x = - 10 \div 2 \\ x = - 5$

$2x - 1 = 6x - 4 \\ 2x - 6x = - 4 + 1 \\ - 4x = - 3 \\ x = \frac{3}{4}$
$4x - 2 = 2 \\ 4x = 2 + 2 \\ 4x = 4 \\ x = 4 \div 4 \\ x = 1$


$3 - 2x = - 3 \\ - 2x = - 3 - 3 \\ - 2x = - 6 \\ x = - 6 \div - 2 \\ x = 3$

$6x - 8 = 7x - 3 \\ 6x - 7x = - 3 + 8 \\ - 1x = 5 \\ x = 5 \div - 1 \\ x = - 5$

$3x - 7 = 6x - 4 \\ 3x - 6x = - 4 + 7 \\ - 3x = 3 \\ x = 3 \div - 3 \\ x = - 1$
