Work: Find the solution of equation 4173442.74-x-3961144.26-x = （4173442.74-x-2000000）*0.15+450000 .
Question type: Equation
Solution:Original question:
208672137 50 | − | x | − | 198057213 50 | − | x | = | ( | 208672137 50 | − | x | − | 2000000 | ) | × | 3 20 | + | 450000 |
| Left side of the equation = | 5307462 25 | − | 2 | x |
5307462 25 | − | 2 | x | = | ( | 208672137 50 | − | x | − | 2000000 | ) | × | 3 20 | + | 450000 |
| Right side of the equation = | 208672137 50 | × | 3 20 | − | x | × | 3 20 | − | 2000000 | × | 3 20 | + | 450000 |
| = | 626016411 1000 | − | x | × | 3 20 | − | 300000 | + | 450000 |
| = | 776016411 1000 | − | 3 20 | x |
5307462 25 | − | 2 | x | = | 776016411 1000 | − | 3 20 | x |
Transposition :
| - | 2 | x | + | 3 20 | x | = | 776016411 1000 | − | 5307462 25 |
Combine the items on the left of the equation:
| - | 37 20 | x | = | 776016411 1000 | − | 5307462 25 |
x≈-304712.395135 , keep 6 decimal places
