Work: Find the solution of equation 361/3150+x/2820+0.47x/2640 = 0.99 .
Question type: Equation
Solution:Original question:
| 361 | ÷ | 3150 | + | x | ÷ | 2820 | + | 47 100 | x | ÷ | 2640 | = | 99 100 |
| Left side of the equation = | 361 3150 | + | x | × | 1 2820 | + | 47 264000 | x |
| = | 361 3150 | + | 2203 4136000 | x |
361 3150 | + | 2203 4136000 | x | = | 99 100 |
Transposition :
2203 4136000 | x | = | 99 100 | − | 361 3150 |
Combine the items on the right of the equation:
2203 4136000 | x | = | 1103 1260 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1103 1260 | ÷ | 2203 4136000 |
| = | 1103 1260 | × | 4136000 2203 |
| = | 1103 63 | × | 206800 2203 |
We obtained :
| x | = | 228100400 138789 |
Convert the result to decimal form :
| x | = | 1643.504889 |
