1 / x + 1 / 2x + 1 / 3 = 0, solve the equation

1 / x + 1 / 2x + 1 / 3 = 0, solve the equation

1/x+1/2x+1/3=0
1/x+1/2x=-1/3
2+1=-2x/3
3=-2x/3
x=-4.5

Solve the equation: 3 (2x-3) - 1 / 3 (3-2x) = 7 (3-2x) - 1 / 7 (2x-3), find x,

3（2 x - 3）- （1 / 3）（3 - 2 x）= 7 （3 - 2 x）- （1 / 7）（2 x - 3）3（2 x - 3）+ （1 / 3）（2 x - 3）= - 7（2 x - 3）- （1 / 7）（2 x - 3）3（2 x - 3）+ （1 / 3）（2 x - 3）+ 7（2 x - 3）+ （1 / 7...

6.2x-x = 41.6

5.2x=41.6 x=8

4、 Solving equation 1.2 + 2x = 6.4 △ 2 (x + 1.7) △ 3 = 1.4
4、 Solving the equation
1.2+2X＝6.4÷2
（X+1.7）÷3＝1.4
26.4X+18X＝66.6
(x-16) × 5 = 45 (test)
