五年级解方程题，不要答案

Answer 1

2x+17=35
3x-64=11
12+8x=52
0.8x-4.2=2.2
2x+5=10
3x-15=75
4x+4o=320
3x+77=122
5x-1.6=0.6
6x-4=20
10x-0.6=2.4
500-12x=140

Answer 2

2x＋0.82＝8.2 3＋0.5x＝7
7.8÷x＝2.6 80x÷4＝12

5－0.9x＝2.75 2x＋0.4x=48
6－2x＋6x=18 35x＋13x=9.6

0.52×5－4x=0.6 0.7(x＋0.9)=42

1.3x＋2.4×3=12.4 (3－0.5) x =12

5x＋2x=1.4＋0.07 6.25×4=25＋4x

(21－5x）÷2=x

Answer 3

(1)9X+3X=3.6 (2)8X-0.5X=120 (3)4.5X-X=14 (4)2.8X+7X=44.1 (5)X+5.5X=13 (6)9X-3X=3.6 (7)1.2X-X=9 (8)(3X+X)x2=120
