《2025年猿辅导暑假一本通六年级》

解方程。
$9x-(4-x)= 16$ $10(x+12)= 320$
$20x= 24(x-6)$ $5(4x-18)= 150$
$2(x+x+0.5)= 9.8$ $(91-4x)÷3= 13$
$3(x+2)= 4(x+1)$ $2(x+6)= 7x-3$

答案：

解方程：

1. $9x - (4 - x) = 16$

解：$9x - 4 + x = 16$

$10x = 20$

$x = 2$

2. $10(x + 12) = 320$

解：$x + 12 = 32$

$x = 20$

3. $20x = 24(x - 6)$

解：$20x = 24x - 144$

$-4x = -144$

$x = 36$

4. $5(4x - 18) = 150$

解：$4x - 18 = 30$

$4x = 48$

$x = 12$

5. $2(x + x + 0.5) = 9.8$

解：$2(2x + 0.5) = 9.8$

$4x + 1 = 9.8$

$4x = 8.8$

$x = 2.2$

6. $(91 - 4x)÷3 = 13$

解：$91 - 4x = 39$

$-4x = -52$

$x = 13$

7. $3(x + 2) = 4(x + 1)$

解：$3x + 6 = 4x + 4$

$-x = -2$

$x = 2$

8. $2(x + 6) = 7x - 3$

解：$2x + 12 = 7x - 3$

$-5x = -15$

$x = 3$
