Work: Find the solution of equation X+1.05*X+1.05*1.05*X = 39600 .
Question type: Equation
Solution:Original question:
| X | + | 21 20 | X | + | 21 20 | × | 21 20 | X | = | 39600 |
| Left side of the equation = | X | + | 21 20 | X | + | 441 400 | X |
| = | 1261 400 | X |
1261 400 | X | = | 39600 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 39600 | ÷ | 1261 400 |
| = | 39600 | × | 400 1261 |
We obtained :
| X | = | 15840000 1261 |
Convert the result to decimal form :
| X | = | 12561.459159 |
