Work: Find the solution of equation x = 89.29+8.3+1+6.69+(x/1.09*9%)*1.12+x/1.09*12% .
Question type: Equation
Solution:Original question:
| x | = | 8929 100 | + | 83 10 | + | 1 | + | 669 100 | + | ( | x | ÷ | 109 100 | × | 9 100 | ) | × | 28 25 | + | x | ÷ | 109 100 | × | 12 100 |
| Right side of the equation = | 8929 100 | + | 83 10 | + | 1 | + | 669 100 | + | ( | x | ÷ | 109 100 | × | 9 100 | ) | × | 28 25 | + | x | × | 12 109 |
| = | 2632 25 | + | ( | x | ÷ | 109 100 | × | 9 100 | ) | × | 28 25 | + | 12 109 | x |
| x | = | 2632 25 | + | ( | x | ÷ | 109 100 | × | 9 100 | ) | × | 28 25 | + | 12 109 | x |
| Right side of the equation = | 2632 25 | + | x | ÷ | 109 100 | × | 9 100 | × | 28 25 | + | 12 109 | x |
| = | 2632 25 | + | x | × | 252 2725 | + | 12 109 | x |
| = | 2632 25 | + | 552 2725 | x |
| x | = | 2632 25 | + | 552 2725 | x |
Transposition :
| x | − | 552 2725 | x | = | 2632 25 |
Combine the items on the left of the equation:
2173 2725 | x | = | 2632 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2632 25 | ÷ | 2173 2725 |
| = | 2632 25 | × | 2725 2173 |
| = | 2632 | × | 109 2173 |
We obtained :
| x | = | 286888 2173 |
Convert the result to decimal form :
| x | = | 132.02393 |
