Work: Find the solution of equation 200/87+X/135-1 = 0.00305（1600+X） .
Question type: Equation
Solution:Original question:
| 200 | ÷ | 87 | + | X | ÷ | 135 | − | 1 | = | 61 20000 | ( | 1600 | + | X | ) |
| Left side of the equation = | 200 87 | + | X | × | 1 135 | − | 1 |
| = | 113 87 | + | 1 135 | X |
113 87 | + | 1 135 | X | = | 61 20000 | ( | 1600 | + | X | ) |
| Right side of the equation = | 61 20000 | × | 1600 | + | 61 20000 | X |
| = | 122 25 | + | 61 20000 | X |
113 87 | + | 1 135 | X | = | 122 25 | + | 61 20000 | X |
Transposition :
1 135 | X | − | 61 20000 | X | = | 122 25 | − | 113 87 |
Combine the items on the left of the equation:
2353 540000 | X | = | 122 25 | − | 113 87 |
Combine the items on the right of the equation:
2353 540000 | X | = | 7789 2175 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 7789 2175 | ÷ | 2353 540000 |
| = | 7789 2175 | × | 540000 2353 |
| = | 7789 29 | × | 7200 2353 |
We obtained :
| X | = | 56080800 68237 |
Convert the result to decimal form :
| X | = | 821.853247 |
