Work: Find the solution of equation 32-x/30 = 1/10 .
Question type: Equation
Solution:Original question:
| 32 | − | x | ÷ | 30 | = | 1 | ÷ | 10 |
| Right side of the equation = | 1 10 |
| 32 | − | 1 30 | x | = | 1 10 |
Transposition :
| - | 1 30 | x | = | 1 10 | − | 32 |
Combine the items on the right of the equation:
| - | 1 30 | x | = | - | 319 10 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
319 10 | = | 1 30 | 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 :
1 30 | x | = | 319 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 319 10 | ÷ | 1 30 |
| = | 319 10 | × | 30 |
| = | 319 | × | 3 |
We obtained :
| x | = | 957 |
