一元一次方程的解法练习题如下：
1. 解方程：3x + 5 = 19
2. 解方程：2(x 3) = 8
3. 解方程：5 3x = 2x + 1
4. 解方程：4x 2 = 3x + 7
5. 解方程：3(x + 2) 2x = 8
6. 解方程：2x + 5 = 3(x 1)
7. 解方程：5x 3 = 2x + 4
8. 解方程：x + 4 = 2(x 3)
9. 解方程：3x 7 = 2(x + 1)
10. 解方程：4x + 2 = 3(2x 1)
请根据一元一次方程的解法，依次求解上述方程。解法如下：
1. 3x + 5 = 19
3x = 19 5
3x = 14
x = 14 / 3
x = 4.67（约）
2. 2(x 3) = 8
2x 6 = 8
2x = 8 + 6
2x = 14
x = 14 / 2
x = 7
3. 5 3x = 2x + 1
5 1 = 2x + 3x
4 = 5x
x = 4 / 5
x = 0.8
4. 4x 2 = 3x + 7
4x 3x = 7 + 2
x = 9
5. 3(x + 2) 2x = 8
3x + 6 2x = 8
x + 6 = 8
x = 8 6
x = 2
6. 2x + 5 = 3(x 1)
2x + 5 = 3x 3
5 + 3 = 3x 2x
8 = x
7. 5x 3 = 2x + 4
5x 2x = 4 + 3
3x = 7
x = 7 / 3
x = 2.33（约）
8. x + 4 = 2(x 3)
x + 4 = 2x 6
4 + 6 = 2x x
10 = x
9. 3x 7 = 2(x + 1)
3x 7 = 2x + 2
3x 2x = 2 + 7
x = 9
10. 4x + 2 = 3(2x 1)
4x + 2 = 6x 3
2 + 3 = 6x 4x
5 = 2x
x = 5 / 2
x = 2.5
以上就是一元一次方程的解法练习题及其解答。
