Work: Find the solution of equation 10x+[6*(x*0.9)] = 172.47 .
Question type: Equation
Solution:Original question:
| 10 | x | + | ( | 6 | ( | x | × | 9 10 | ) | ) | = | 17247 100 |
| Left side of the equation = | 10 | x | + | 6 | ( | x | × | 9 10 | ) |
| = | 10 | x | + | 6 | x | × | 9 10 |
| = | 10 | x | + | 27 5 | x |
| = | 77 5 | x |
77 5 | x | = | 17247 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 17247 100 | ÷ | 77 5 |
| = | 17247 100 | × | 5 77 |
| = | 17247 20 | × | 1 77 |
We obtained :
| x | = | 17247 1540 |
Convert the result to decimal form :
| x | = | 11.199351 |
