Work: Find the solution of equation x = 0.278(666.6-x)(933.3-x) .
Question type: Equation
Solution:Original question:
| x | = | 139 500 | ( | 3333 5 | − | x | ) | ( | 9333 10 | − | x | ) |
| Right side of the equation = | 139 500 | × | 3333 5 | ( | 9333 10 | − | x | ) | − | 139 500 | x | ( | 9333 10 | − | x | ) |
| = | 463287 2500 | ( | 9333 10 | − | x | ) | − | 139 500 | x | ( | 9333 10 | − | x | ) |
| = | 463287 2500 | × | 9333 10 | − | 463287 2500 | x | − | 139 500 | x | ( | 9333 10 | − | x | ) |
| = | 4323857571 25000 | − | 463287 2500 | x | − | 139 500 | x | ( | 9333 10 | − | x | ) |
| = | 4323857571 25000 | − | 463287 2500 | x | − | 139 500 | x | × | 9333 10 | + | 139 500 | x | x |
| = | 4323857571 25000 | − | 463287 2500 | x | − | 1297287 5000 | x | + | 139 500 | x | x |
| = | 4323857571 25000 | − | 2223861 5000 | x | + | 139 500 | x | x |
