Work: Find the solution of equation x-300 = 0.3x .
Question type: Equation
Solution:Original question:
| x | − | 300 | = | 3 10 | x |
Transposition :
| x | − | 3 10 | x | = | 300 |
Combine the items on the left of the equation:
7 10 | x | = | 300 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 300 | ÷ | 7 10 |
| = | 300 | × | 10 7 |
We obtained :
| x | = | 3000 7 |
Convert the result to decimal form :
| x | = | 428.571429 |
