Work: Find the solution of equation （x-400-200）*0.75/6000+2000 = （x-400-450）*0.75/6000+1000 .
Question type: Equation
Solution:Original question:
| ( | x | − | 400 | − | 200 | ) | × | 3 4 | ÷ | 6000 | + | 2000 | = | ( | x | − | 400 | − | 450 | ) | × | 3 4 | ÷ | 6000 | + | 1000 |
| Left side of the equation = | ( | x | − | 400 | − | 200 | ) | × | 1 8000 | + | 2000 |
| ( | x | − | 400 | − | 200 | ) | × | 1 8000 | + | 2000 | = | ( | x | − | 400 | − | 450 | ) | × | 3 4 | ÷ | 6000 | + | 1000 |
| Left side of the equation = | x | × | 1 8000 | − | 400 | × | 1 8000 | − | 200 | × | 1 8000 | + | 2000 |
| = | x | × | 1 8000 | − | 1 20 | − | 1 40 | + | 2000 |
| = | 1 8000 | x | + | 79997 40 |
1 8000 | x | + | 79997 40 | = | ( | x | − | 400 | − | 450 | ) | × | 3 4 | ÷ | 6000 | + | 1000 |
| Right side of the equation = | ( | x | − | 400 | − | 450 | ) | × | 1 8000 | + | 1000 |
1 8000 | x | + | 79997 40 | = | ( | x | − | 400 | − | 450 | ) | × | 1 8000 | + | 1000 |
| Right side of the equation = | x | × | 1 8000 | − | 400 | × | 1 8000 | − | 450 | × | 1 8000 | + | 1000 |
| = | x | × | 1 8000 | − | 1 20 | − | 9 160 | + | 1000 |
| = | 1 8000 | x | + | 159983 160 |
1 8000 | x | + | 79997 40 | = | 1 8000 | x | + | 159983 160 |
Transposition :
1 8000 | x | − | 1 8000 | x | = | 159983 160 | − | 79997 40 |
Combine the items on the left of the equation:
| 0 | x | = | 159983 160 | − | 79997 40 |
Combine the items on the right of the equation:
| 0 | x | = | - | 32001 32 |
