Work: Find the solution of equation 100/135+160/87-100/130-100/216-X/1000 = 0.0007857143（560+X） .
Question type: Equation
Solution:Original question:
| 100 | ÷ | 135 | + | 160 | ÷ | 87 | − | 100 | ÷ | 130 | − | 100 | ÷ | 216 | − | X | ÷ | 1000 | = | 7857143 10000000000 | ( | 560 | + | X | ) |
| Left side of the equation = | 20 27 | + | 160 87 | − | 10 13 | − | 25 54 | − | X | × | 1 1000 |
| = | 9145 6786 | − | 1 1000 | X |
9145 6786 | − | 1 1000 | X | = | 7857143 10000000000 | ( | 560 | + | X | ) |
| Right side of the equation = | 7857143 10000000000 | × | 560 | + | 7857143 10000000000 | X |
| = | 55000001 125000000 | + | 7857143 10000000000 | X |
9145 6786 | − | 1 1000 | X | = | 55000001 125000000 | + | 7857143 10000000000 | X |
Transposition :
| - | 1 1000 | X | − | 7857143 10000000000 | X | = | 55000001 125000000 | − | 9145 6786 |
X≈508.271374 , keep 6 decimal places
