25道方程，递等式【五年级】

Answer 1

3.5x = 140
2x +5 = 40
15x+6x = 168
5x＋1.5 = 4.5
13.7—x = 5.29
4.2 × 3—3x = 5.1
x+15=28
89-x=20
25-x=10

28.62÷0.25÷0.4
101×95 99×25
0.125×0.58×0.008
43.2÷0.36÷0.25
57.96÷4.6÷8.4
0.69÷0.03×15.2
0.456＋6.22＋3.78
15.89＋(6.75－5.89)
4.02＋5.4＋0.98
5.17－1.8－3.2
13.75－(3.75＋6.48)
3.68＋7.56－2.68
7.85+2.34-0.85+4.66
35.6-1.8-15.6-7.2
3.82+2.9+0.18+9.1
9.6+4.8-3.6
7.14-0.53-2.47
5.27+2.86-0.66+1.63
13.35-4.68+2.65
73.8-1.64-13.8-5.36

Answer 2

x＋32＝76 12－x＝4 3÷x=15 9x=1.8 6x－7.3=19.7 5y＋3y=0.24 8m-90=3m 8t-12=24 5x-x=24 7x+x=56 x÷16=35
