Liberation process: 0.4 * (X-9) = 64

x-9=64/0.4
x-9=160
x=160+9
x=169

× - 2 / 3 × = 2 / 9

Liberation process: 2.4 + 0.5 × = 3.8

0.5x=1.4
x=2.8

Liberation process 2x-5 / 2x-8 = X-6 / x-4

2x-5 / 2x-8 = X-6 / x-4 multiply by 2 (x-4)
2x-5=2x-12

There are 17 cows. The eldest son gets half of them, the second one third and the youngest one ninth. How many are each?

Eldest son: 9
Second son: 6
Youngest son: 2
Because half plus one third plus one ninth is 17 out of 18
First add a cow in, then return a cow after sharing, and the total number of cows remains unchanged

(x-2x of X + 2 - x-4x + 4 of x-1) / x-4 of X

The original formula = {(x + 2) / [x (X-2)] - (x-1) / (X-2)} * x / (x-4) = [(x + 2) (X-2) - x (x-1) / [x (X-2)] * x / (x-4) = (x-4-x + x) / [(X-2) (x-4)] = 1 / (X-2)

X-5 / 1-x + 2X-4 / 3 = x + 4x + 2 / 3

5/(X+1)(X-1)-4/(X+3)(X-1)=2/(X+1)(X+3)
5(X+3)-4(X+1)=2(X-1)
X+11=2X-2
X=13
It is proved that x = 13 is the solution of the original equation

84-x / 4 = 26 to solve the equation. 4x-4 × 8.5 = 1.5 × 20 68 △ (24-2x) = 4
