Work: Find the solution of equation （x-200-300）×0.75-55/100 = (x-200)×0.75-55/200 .
Question type: Equation
Solution:Original question:
| ( | x | − | 200 | − | 300 | ) | × | 3 4 | − | 55 | ÷ | 100 | = | ( | x | − | 200 | ) | × | 3 4 | − | 55 | ÷ | 200 |
| Left side of the equation = | ( | x | − | 200 | − | 300 | ) | × | 3 4 | − | 11 20 |
| ( | x | − | 200 | − | 300 | ) | × | 3 4 | − | 11 20 | = | ( | x | − | 200 | ) | × | 3 4 | − | 55 | ÷ | 200 |
| Left side of the equation = | x | × | 3 4 | − | 200 | × | 3 4 | − | 300 | × | 3 4 | − | 11 20 |
| = | x | × | 3 4 | − | 150 | − | 225 | − | 11 20 |
| = | 3 4 | x | − | 7511 20 |
3 4 | x | − | 7511 20 | = | ( | x | − | 200 | ) | × | 3 4 | − | 55 | ÷ | 200 |
| Right side of the equation = | ( | x | − | 200 | ) | × | 3 4 | − | 11 40 |
3 4 | x | − | 7511 20 | = | ( | x | − | 200 | ) | × | 3 4 | − | 11 40 |
| Right side of the equation = | x | × | 3 4 | − | 200 | × | 3 4 | − | 11 40 |
| = | x | × | 3 4 | − | 150 | − | 11 40 |
| = | 3 4 | x | − | 6011 40 |
3 4 | x | − | 7511 20 | = | 3 4 | x | − | 6011 40 |
Transposition :
3 4 | x | − | 3 4 | x | = | - | 6011 40 | + | 7511 20 |
Combine the items on the left of the equation:
| 0 | x | = | - | 6011 40 | + | 7511 20 |
Combine the items on the right of the equation:
| 0 | x | = | 9011 40 |
Error: This Equation has no solution!!
