Work: Find the solution of equation 1200+0.5x = 615.9+(18.96*(x-45)/2.96796)-(3.4*(x-45)*(x-45)/(2*2.96796) ) .
Question type: Equation
Solution:Original question:
| 1200 | + | 1 2 | x | = | 6159 10 | + | ( | 474 25 | ( | x | − | 45 | ) | ÷ | 74199 25000 | ) | − | ( | 17 5 | ( | x | − | 45 | ) | ( | x | − | 45 | ) | ÷ | ( | 2 | × | 74199 25000 | ) | ) |
| 1200 | + | 1 2 | x | = | 6159 10 | + | 474 25 | ( | x | − | 45 | ) | ÷ | 74199 25000 | − | ( | 17 5 | ( | x | − | 45 | ) | ( | x | − | 45 | ) | ÷ | ( | 2 | × | 74199 25000 | ) | ) |
| 1200 | + | 1 2 | x | = | 6159 10 | + | 158000 24733 | ( | x | − | 45 | ) | − | ( | 17 5 | ( | x | − | 45 | ) | ( | x | − | 45 | ) | ÷ | ( | 2 | × | 74199 25000 | ) | ) |
| 1200 | + | 1 2 | x | = | 6159 10 | + | 158000 24733 | x | − | 158000 24733 | × | 45 | − | ( | 17 5 | ( | x | − | 45 | ) | ( | x | − | 45 | ) | ÷ | ( | 2 | × | 74199 25000 | ) | ) |
| 1200 | + | 1 2 | x | = | 6159 10 | + | 158000 24733 | x | − | 7110000 24733 | − | ( | 17 5 | ( | x | − | 45 | ) | ( | x | − | 45 | ) | ÷ | ( | 2 | × | 74199 25000 | ) | ) |
| 1200 | + | 1 2 | x | = | 81230547 247330 | + | 158000 24733 | x | − | ( | 17 5 | ( | x | − | 45 | ) | ( | x | − | 45 | ) | ÷ | ( | 2 | × | 74199 25000 | ) | ) |
| 1200 | + | 1 2 | x | = | 81230547 247330 | + | 158000 24733 | x | − | 17 5 | ( | x | − | 45 | ) | ( | x | − | 45 | ) | ÷ | ( | 2 | × | 74199 25000 | ) |
| Multiply both sides of the equation by: | ( | 2 | × | 74199 25000 | ) |
| 1200 | ( | 2 | × | 74199 25000 | ) | + | 1 2 | x | ( | 2 | × | 74199 25000 | ) | = | 81230547 247330 | ( | 2 | × | 74199 25000 | ) | + | 158000 24733 | x | ( | 2 | × | 74199 25000 | ) | − | 17 5 | ( | x | − | 45 | ) | ( | x | − | 45 | ) |
| 1200 | × | 2 | × | 74199 25000 | + | 1 2 | x | ( | 2 | × | 74199 25000 | ) | = | 81230547 247330 | ( | 2 | × | 74199 25000 | ) | + | 158000 24733 | x | ( | 2 | × | 74199 25000 | ) | − | 17 5 | ( | x | − | 45 | ) | ( | x | − | 45 | ) |
| 1200 | × | 2 | × | 74199 25000 | + | 1 2 | x | ( | 2 | × | 74199 25000 | ) | = | 81230547 247330 | × | 2 | × | 74199 25000 | + | 158000 24733 | x | ( | 2 | × | 74199 25000 | ) | − | 17 5 | ( | x | − | 45 | ) | ( | x | − | 45 | ) |
