1764 25 | x | − | x | ( | 3 5 | + | 2 | × | 71 200 | ) | ( | 3 5 | + | 2 | × | 71 200 | ) | = | 1490 |
| Left side of the equation = | 1764 25 | x | − | x | × | 3 5 | ( | 3 5 | + | 2 | × | 71 200 | ) | − | x | × | 2 | × | 71 200 | ( | 3 5 | + | 2 | × | 71 200 | ) |
| = | 1764 25 | x | − | x | × | 3 5 | ( | 3 5 | + | 2 | × | 71 200 | ) | − | x | × | 71 100 | ( | 3 5 | + | 2 | × | 71 200 | ) |
| = | 1764 25 | x | − | x | × | 3 5 | × | 3 5 | − | x | × | 3 5 | × | 2 | × | 71 200 | − | x | × | 71 100 | ( | 3 5 | + | 2 | × | 71 200 | ) |
| = | 1764 25 | x | − | x | × | 9 25 | − | x | × | 213 500 | − | x | × | 71 100 | ( | 3 5 | + | 2 | × | 71 200 | ) |
| = | 34887 500 | x | − | x | × | 71 100 | ( | 3 5 | + | 2 | × | 71 200 | ) |
| = | 34887 500 | x | − | x | × | 71 100 | × | 3 5 | − | x | × | 71 100 | × | 2 | × | 71 200 |
| = | 34887 500 | x | − | x | × | 213 500 | − | x | × | 5041 10000 |
| = | 688439 10000 | x |
688439 10000 | x | = | 1490 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1490 | ÷ | 688439 10000 |
| = | 1490 | × | 10000 688439 |
We obtained :
| x | = | 14900000 688439 |
Convert the result to decimal form :
| x | = | 21.643167 |
