X+3.5 =8 5x =20.5 x-4.8 =23.56 x÷3.6 =8.2

7.4+x =30 x-308 =692 2.5x =75 x÷6.4 =20

3.6x =7.2 x+38.9 =80 x-2.4 =21 x÷34 =2.7

126÷X=42 13+x=28.5 2.4X=26.4 10-x=8.5

3.5x = 140 2x +5 = 40 13x- 59.71= 5.29 54-X=24

4.2×3—3x =5.11 5x+6x = 168 5x+1.5 = 4.5 7X-7=49

x+3.86=5.46 17.89-x=12.89 40.8+x=57.3 3x+2×6=30

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

5+0.9x﹦275 2x+0.4x=48 6+6x=18 35x+13x=9.6

0.52×5+4x=16 0.7(x+0.9)=42 1.3x+2.4×3=12.4 24x-8x=28.8

78+4x=84 4.5×2+5x=180 8x-7.2×5=12 13+A=28.5

(7-1.4)x=2.8 9x-5.2×6=4.8 7x-0.8x=9.3 x÷0.84=2.3

13+x=98.5 3x-24=9 x-0.84x=0.8 x÷0.26=0.52

0.25x+3.75=12 x+1.8×2=7.5 x÷7.2+3.8=15 0.6x+x=24

48+5x=63 17.6+2.4x=50 5x-1.5x=28 2x÷15=4

(6-2.5)x=14.7 (x-4.5)÷7=1.6 6(x+8.9)=72

(x+8.6)÷2.4=6.4 x-0.3x-0.5x=20 4(x-7.8)=31.2

1.5(48-2x)=48 (x+32)÷24=2.5 4x-2×6=4

0.7x=4.2 x-9=11 3x=2.1 x÷8=15

4.8÷1.2+0.5x=8.5 2.5x-0.6×1.5=6.6 16÷x=8

4x+2=7×8 12.5x-0.9x=52.2 2x+2.8×2=10.5×4
