解方程练习题
基本练习:
x+4=10 x-12=34 8x=96
4x-30=0 8.3x-2x=63 x÷10 = 5.2
提高练习:
3x+ 7x +10 = 90 3(x - 12)+ 23 = 35
5x -18 = 3–2x (7x - 4)+3(x - 2)= 2x +6
综合练习
80÷x=20 12x+8x-12=28
3(2x-1)+10=37 1.6x+3.4x-x-5=27
2(3x-4)+(4-x)=4x 3(x+2)÷5=(x+2)
7x-8=2x+27
(3x+5)÷2=(5x-9)÷3
能力升级题
7(4-x)=9(x-4) 128-5(2x+3)=73
1.7x+4.8+0.3x=7.8
3(x +1 )÷(2x –
)= 6 x÷0.24=100 4
