Work: Find the solution of equation X1*12+1.5%X1-X1 = 99.89 .
Question type: Equation
Solution:Original question:
| X | × | 1 | × | 12 | + | 3 200 | X | × | 1 | − | X | × | 1 | = | 9989 100 |
| Left side of the equation = | X | × | 12 | + | 3 200 | X | − | X | × | 1 |
| = | 2203 200 | X |
2203 200 | X | = | 9989 100 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 9989 100 | ÷ | 2203 200 |
| = | 9989 100 | × | 200 2203 |
| = | 9989 | × | 2 2203 |
We obtained :
| X | = | 19978 2203 |
Convert the result to decimal form :
| X | = | 9.068543 |
