$0.25x - 0.75 × 2 = 26.5$
$3.2 × 3 - 3x = 3.3$
$10x - 7x + 9 = 18$
$19x - 2 = 17x + 58$
$8x - 8 = 6x$
$12x = 300 - 3x$
$4x - 6 = 3x - 1$
$3x + 8 = 5x - 62$

答案：

解：

1. $0.25x - 0.75×2 = 26.5$

$0.25x - 1.5 = 26.5$

$0.25x = 26.5 + 1.5$

$0.25x = 28$

$x = 28÷0.25$

$x = 112$

2. $3.2×3 - 3x = 3.3$

$9.6 - 3x = 3.3$

$-3x = 3.3 - 9.6$

$-3x = -6.3$

$x = (-6.3)÷(-3)$

$x = 2.1$

3. $10x - 7x + 9 = 18$

$3x + 9 = 18$

$3x = 18 - 9$

$3x = 9$

$x = 9÷3$

$x = 3$

4. $19x - 2 = 17x + 58$

$19x - 17x = 58 + 2$

$2x = 60$

$x = 60÷2$

$x = 30$

5. $8x - 8 = 6x$

$8x - 6x = 8$

$2x = 8$

$x = 8÷2$

$x = 4$

6. $12x = 300 - 3x$

$12x + 3x = 300$

$15x = 300$

$x = 300÷15$

$x = 20$

7. $4x - 6 = 3x - 1$

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

$x = 5$

8. $3x + 8 = 5x - 62$

$8 + 62 = 5x - 3x$

$70 = 2x$

$x = 70÷2$

$x = 35$
