Junior high school) 50x(x-2+8)=(50+10)x(x-2-5) solution: 50x-100+400=60x-120-300

50x+300=60x-420

10x=-720

x=72If the landlord is not a junior high school... The next few will not be understood.。。

Primary) 50x+300=60x-420

60x-420=50x+300 (swap positions)60x-420+420=50x+300+42060x=50x+720

60x-50x=50x+720-50x

10x=720

x=72

50x（x-2+8）=（50+10）x（x-2-5)50x-100+400=60x-120-300100+400+120+300=60x-50x10x=720

8x-（20-x）*5=20

8x-100+5x=20

13x=120

x=120 acres of pure trillion 13

x = 9 and pants ruined 13 of the rent of 3

Here's how: 1. Add two x's together to make 2x.

2. Move 8 minus 50 to the right to form 20 minus 8 plus 50.

3. The difference between the two sides is calculated to be 2x equal to 62.

4. Calculated x is equal to 31. That's all there is to the method of solving this equation. Solving an equation is the family modulo process of finding the values of all the unknowns in the equation.

2/5x+50=（x+50)×5/11

2/5x+50=5/11x+250/11

2/5x-5/11x=250/11-550/113/55x=-300/11

x=-300/11×55/3

In the calculation process of x=500, it is necessary to find out the minimum excavation Zen dust dispersion mother, and the denominator is the same calculation, which can be eliminated.

Summary. The specific calculation process is as follows: 2 5 x ten 50 = 50% 2 5 x ten 50 = 50% x solve the equation.

The specific calculation process is as follows: 2 5x ten 50 = 50% This problem needs to first turn the fraction into a decimal place, and then use the algorithm of shifting terms to move the term that does not contain x to the right of the equal sign.

In this way, you can find the value of x

Is there any other way?

Yes oh 2 5x ten 50 = 50%.

This method uses the property of the equation to subtract both sides of the equal sign at the same time, and you can also find the value of x

Contradictory equations, no solution.

Subtract x from both sides to get 75=28, which is ridiculous.

This equation does not hold and the unknown number is 0 after shifting.
