Work: Find the solution of equation X/87-25/1900-3/44.7 = 0.00167(x+28） .
Question type: Equation
Solution:Original question:
| X | ÷ | 87 | − | 25 | ÷ | 1900 | − | 3 | ÷ | 447 10 | = | 167 100000 | ( | X | + | 28 | ) |
| Left side of the equation = | X | × | 1 87 | − | 1 76 | − | 10 149 |
| = | 1 87 | X | − | 909 11324 |
1 87 | X | − | 909 11324 | = | 167 100000 | ( | X | + | 28 | ) |
| Right side of the equation = | 167 100000 | X | + | 167 100000 | × | 28 |
| = | 167 100000 | X | + | 1169 25000 |
1 87 | X | − | 909 11324 | = | 167 100000 | X | + | 1169 25000 |
Transposition :
1 87 | X | − | 167 100000 | X | = | 1169 25000 | + | 909 11324 |
Combine the items on the left of the equation:
85471 8700000 | X | = | 1169 25000 | + | 909 11324 |
Combine the items on the right of the equation:
85471 8700000 | X | = | 8990689 70775000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 8990689 70775000 | ÷ | 85471 8700000 |
| = | 8990689 70775000 | × | 8700000 85471 |
| = | 8990689 2831 | × | 348 85471 |
We obtained :
| X | = | 3128759772 241968401 |
Convert the result to decimal form :
| X | = | 12.930448 |
