Work: Find the solution of equation X-X*0.065-(X+1500000)*0.0003 = 1500000 .
Question type: Equation
Solution:Original question:
| X | − | X | × | 13 200 | − | ( | X | + | 1500000 | ) | × | 3 10000 | = | 1500000 |
| Left side of the equation = | 187 200 | X | − | ( | X | + | 1500000 | ) | × | 3 10000 |
187 200 | X | − | ( | X | + | 1500000 | ) | × | 3 10000 | = | 1500000 |
| Left side of the equation = | 187 200 | X | − | X | × | 3 10000 | − | 1500000 | × | 3 10000 |
| = | 187 200 | X | − | X | × | 3 10000 | − | 450 |
| = | 9347 10000 | X | − | 450 |
9347 10000 | X | − | 450 | = | 1500000 |
Transposition :
9347 10000 | X | = | 1500000 | + | 450 |
Combine the items on the right of the equation:
9347 10000 | X | = | 1500450 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 1500450 | ÷ | 9347 10000 |
| = | 1500450 | × | 10000 9347 |
We obtained :
| X | = | 15004500000 9347 |
