Work: Find the solution of equation 15% = (1.019-X)/1.019 .
Question type: Equation
Solution:Original question:
15 100 | = | ( | 1019 1000 | − | X | ) | ÷ | 1019 1000 |
| Right side of the equation = | 1019 1000 | × | 1000 1019 | − | X | × | 1000 1019 |
| = | 1019 1019 | − | X | × | 1000 1019 |
15 100 | = | 1019 1019 | − | 1000 1019 | X |
Transposition :
1000 1019 | X | = | 1019 1019 | − | 15 100 |
Combine the items on the right of the equation:
1000 1019 | X | = | 17323 20380 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 17323 20380 | ÷ | 1000 1019 |
| = | 17323 20380 | × | 1019 1000 |
We obtained :
| X | = | 17652137 20380000 |
By reducing fraction, we can get:
| X | = | 17323 20000 |
Convert the result to decimal form :
| X | = | 0.86615 |
