Work: Find the solution of equation X/87-10/500-20/333 = 0.00167（X+30） .
Question type: Equation
Solution:Original question:
| X | ÷ | 87 | − | 10 | ÷ | 500 | − | 20 | ÷ | 333 | = | 167 100000 | ( | X | + | 30 | ) |
| Left side of the equation = | X | × | 1 87 | − | 1 50 | − | 20 333 |
| = | 1 87 | X | − | 1333 16650 |
1 87 | X | − | 1333 16650 | = | 167 100000 | ( | X | + | 30 | ) |
| Right side of the equation = | 167 100000 | X | + | 167 100000 | × | 30 |
| = | 167 100000 | X | + | 501 10000 |
1 87 | X | − | 1333 16650 | = | 167 100000 | X | + | 501 10000 |
Transposition :
1 87 | X | − | 167 100000 | X | = | 501 10000 | + | 1333 16650 |
Combine the items on the left of the equation:
85471 8700000 | X | = | 501 10000 | + | 1333 16650 |
Combine the items on the right of the equation:
85471 8700000 | X | = | 433433 3330000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 433433 3330000 | ÷ | 85471 8700000 |
| = | 433433 3330000 | × | 8700000 85471 |
| = | 433433 111 | × | 290 85471 |
We obtained :
| X | = | 125695570 9487281 |
Convert the result to decimal form :
| X | = | 13.248851 |
