Solution:Original question:
| ( | 93 5 | × | 343 20 | + | 1249 50 | × | 311 25 | + | 2301 100 | × | 6 | + | 161 25 | ( | - | 139 50 | ) | + | 1353 100 | ( | - | 149 25 | ) | + | 336 25 | x | ) | = | 1899 100 |
| Left side of the equation = | 93 5 | × | 343 20 | + | 1249 50 | × | 311 25 | + | 2301 100 | × | 6 | + | 161 25 | ( | - | 139 50 | ) | + | 1353 100 | ( | - | 149 25 | ) | + | 336 25 | x |
| = | 31899 100 | + | 388439 1250 | + | 6903 50 | + | 161 25 | ( | - | 139 50 | ) | + | 1353 100 | ( | - | 149 25 | ) | + | 84 625 | x |
| = | 1919503 2500 | + | 161 25 | ( | - | 139 50 | ) | + | 1353 100 | ( | - | 149 25 | ) | + | 84 625 | x |
| = | 1919503 2500 | − | 161 25 | × | 139 50 | + | 1353 100 | ( | - | 149 25 | ) | + | 84 625 | x |
| = | 1919503 2500 | − | 22379 1250 | + | 1353 100 | ( | - | 149 25 | ) | + | 84 625 | x |
| = | 374949 500 | + | 1353 100 | ( | - | 149 25 | ) | + | 84 625 | x |
| = | 374949 500 | − | 1353 100 | × | 149 25 | + | 84 625 | x |
| = | 374949 500 | − | 201597 2500 | + | 84 625 | x |
| = | 418287 625 | + | 84 625 | x |
418287 625 | + | 84 625 | x | = | 1899 100 |
Transposition :
84 625 | x | = | 1899 100 | − | 418287 625 |
Combine the items on the right of the equation:
84 625 | x | = | - | 1625673 2500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 1625673 2500 | ÷ | 84 625 |
| = | - | 1625673 2500 | × | 625 84 |
| = | - | 77413 4 | × | 1 4 |
We obtained :
| x | = | - | 77413 16 |
Convert the result to decimal form :
| x | = | - 4838.3125 |
