| = | 2592324 25 | + | 25758 5 | x |
2592324 25 | + | 25758 5 | x | = | 9 10 | × | 509 | × | 4587 10 | + | 339 | × | 4969 10 | − | 308 | × | 4431 10 | − | 9 10 | × | 402 | × | 2199 5 |
| Right side of the equation = | 21013047 100 | + | 1684491 10 | − | 682374 5 | − | 3977991 25 |
| = | 8298513 100 |
2592324 25 | + | 25758 5 | x | = | 8298513 100 |
Transposition :
25758 5 | x | = | 8298513 100 | − | 2592324 25 |
Combine the items on the right of the equation:
25758 5 | x | = | - | 2070783 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 2070783 100 | ÷ | 25758 5 |
| = | - | 2070783 100 | × | 5 25758 |
| = | - | 230087 20 | × | 1 2862 |
We obtained :
| x | = | - | 230087 57240 |
Convert the result to decimal form :
| x | = | - 4.019689 |
