Work: Find the solution of equation x = 66.48+12.39+1+(x/1.09*0.09)*1.12+x/1.09*12% .
Question type: Equation
Solution:Original question:
| x | = | 1662 25 | + | 1239 100 | + | 1 | + | ( | x | ÷ | 109 100 | × | 9 100 | ) | × | 28 25 | + | x | ÷ | 109 100 | × | 12 100 |
| Right side of the equation = | 1662 25 | + | 1239 100 | + | 1 | + | ( | x | ÷ | 109 100 | × | 9 100 | ) | × | 28 25 | + | x | × | 12 109 |
| = | 7987 100 | + | ( | x | ÷ | 109 100 | × | 9 100 | ) | × | 28 25 | + | 12 109 | x |
| x | = | 7987 100 | + | ( | x | ÷ | 109 100 | × | 9 100 | ) | × | 28 25 | + | 12 109 | x |
| Right side of the equation = | 7987 100 | + | x | ÷ | 109 100 | × | 9 100 | × | 28 25 | + | 12 109 | x |
| = | 7987 100 | + | x | × | 252 2725 | + | 12 109 | x |
| = | 7987 100 | + | 552 2725 | x |
| x | = | 7987 100 | + | 552 2725 | x |
Transposition :
| x | − | 552 2725 | x | = | 7987 100 |
Combine the items on the left of the equation:
2173 2725 | x | = | 7987 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 7987 100 | ÷ | 2173 2725 |
| = | 7987 100 | × | 2725 2173 |
| = | 7987 4 | × | 109 2173 |
We obtained :
| x | = | 870583 8692 |
Convert the result to decimal form :
| x | = | 100.159112 |
