3x-2=1.6   5x÷2=25   x-18=2.9+0.71 8x+x=2.97   14x-3x=1.21   1.6×25-5x=2

（1）3x-2=1.6，       3x-2+2=1.6+2，           3x=3.6，        3x÷3=3.6÷3，             x=1.2；（2）5x÷2=25，  5x÷2×2=25×2，         5x=50，     5x÷5=50÷5，         x=10；（3）x-18=2.9+0.71，  x-18+18=3.61+18，        x=21.61；（4）8x+x=2.97，       9x=2.97，    9x÷9=2.97÷9，         x=0.33；（5）14x-3x=1.21，        11x=1.21，    11x÷11=1.21÷11，          x=0.11；（6）1.6×25-5x=2，          40-5x=2，       40-5x+5x=2+5x，           2+5x=40，         2+5x-2=40-2，             5x=38，          5x÷5=38÷5，               x=7.2．

Solve the equation 4 / 5x (1-25%) = 1.4
160×25％-1.3x=17.9

4/5x÷（1-25％）=1.4
16/15x=1.4
16x=21
x=21/16
160×25％-1.3x=17.9
40-1.3x=17.9
1.3x=22.1
13x=221
x=17

To solve the equation: 1 and 6 / 5x - 2 and 4 / 1 = x + 1 and 2 / 1

11 / 6x-9 / 4 = 3 / 2 + X, the solution is x = 9 / 2
