Work: Find the solution of equation 540/87+240/X-1.6-800/1650-36/44.7 = 4416*0.0012 .
Question type: Equation
Solution:Original question:
| 540 | ÷ | 87 | + | 240 | ÷ | X | − | 8 5 | − | 800 | ÷ | 1650 | − | 36 | ÷ | 447 10 | = | 4416 | × | 3 2500 |
| Multiply both sides of the equation by: | X |
| 540 | ÷ | 87 | × | X | + | 240 | − | 8 5 | X | − | 800 | ÷ | 1650 | × | X | − | 36 | ÷ | 447 10 | × | X | = | 4416 | × | 3 2500 | X |
Transposition :
| 540 | ÷ | 87 | × | X | − | 8 5 | X | − | 800 | ÷ | 1650 | × | X | − | 36 | ÷ | 447 10 | × | X | − | 4416 | = | - | 240 |
Calculate the items on the left of the equation:
180 29 | X | − | 8 5 | X | − | 16 33 | X | − | 120 149 | X | − | 3312 625 | X | = | - | 240 |
Combine the items on the left of the equation:
| - | 176683516 89120625 | X | = | - | 240 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 240 | = | 176683516 89120625 | X |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
176683516 89120625 | X | = | 240 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 240 | ÷ | 176683516 89120625 |
| = | 240 | × | 89120625 176683516 |
| = | 60 | × | 89120625 44170879 |
We obtained :
| X | = | 5347237500 44170879 |
Convert the result to decimal form :
| X | = | 121.057983 |
