[ 1/7 Equation]
Work: Find the solution of equation x除去53乘上14 = x减去25 .
Question type: Equation
Solution:Original question:
| x | ÷ | 53 | × | 14 | = | x | − | 25 |
| Left side of the equation = | x | × | 14 53 |
14 53 | x | = | x | − | 25 |
Transposition :
14 53 | x | − | x | = | - | 25 |
Combine the items on the left of the equation:
| - | 39 53 | x | = | - | 25 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 25 | = | 39 53 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
39 53 | x | = | 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 25 | ÷ | 39 53 |
| = | 25 | × | 53 39 |
We obtained :
| x | = | 1325 39 |
Convert the result to decimal form :
| x | = | 33.974359 |
[ 2/7 Equation]
Work: Find the solution of equation x除去53乘上14加上1除去2 = x减去25 .
Question type: Equation
Solution:Original question:
| x | ÷ | 53 | × | 14 | + | 1 | ÷ | 2 | = | x | − | 25 |
| Left side of the equation = | x | × | 14 53 | + | 1 2 |
14 53 | x | + | 1 2 | = | x | − | 25 |
Transposition :
14 53 | x | − | x | = | - | 25 | − | 1 2 |
Combine the items on the left of the equation:
| - | 39 53 | x | = | - | 25 | − | 1 2 |
Combine the items on the right of the equation:
| - | 39 53 | x | = | - | 51 2 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
51 2 | = | 39 53 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
39 53 | x | = | 51 2 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 51 2 | ÷ | 39 53 |
| = | 51 2 | × | 53 39 |
| = | 17 2 | × | 53 13 |
We obtained :
| x | = | 901 26 |
Convert the result to decimal form :
| x | = | 34.653846 |
[ 3/7 Equation]
Work: Find the solution of equation x乘上100除去25 = x加上25 .
Question type: Equation
Solution:Original question:
| x | × | 100 | ÷ | 25 | = | x | + | 25 |
| Left side of the equation = | x | × | 4 |
| 4 | x | = | x | + | 25 |
Transposition :
| 4 | x | − | x | = | 25 |
Combine the items on the left of the equation:
| 3 | x | = | 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 25 | ÷ | 3 |
| = | 25 | × | 1 3 |
We obtained :
| x | = | 25 3 |
Convert the result to decimal form :
| x | = | 8.333333 |
