Work: Find the solution of equation X/87-40/1333-40/1650 = 0.00141(X+80) .
Question type: Equation
Solution:Original question:
| X | ÷ | 87 | − | 40 | ÷ | 1333 | − | 40 | ÷ | 1650 | = | 141 100000 | ( | X | + | 80 | ) |
| Left side of the equation = | X | × | 1 87 | − | 40 1333 | − | 4 165 |
| = | 1 87 | X | − | 11932 219945 |
1 87 | X | − | 11932 219945 | = | 141 100000 | ( | X | + | 80 | ) |
| Right side of the equation = | 141 100000 | X | + | 141 100000 | × | 80 |
| = | 141 100000 | X | + | 141 1250 |
1 87 | X | − | 11932 219945 | = | 141 100000 | X | + | 141 1250 |
Transposition :
1 87 | X | − | 141 100000 | X | = | 141 1250 | + | 11932 219945 |
Combine the items on the left of the equation:
87733 8700000 | X | = | 141 1250 | + | 11932 219945 |
Combine the items on the right of the equation:
87733 8700000 | X | = | 9185449 54986250 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 9185449 54986250 | ÷ | 87733 8700000 |
| = | 9185449 54986250 | × | 8700000 87733 |
| = | 9185449 14663 | × | 2320 87733 |
We obtained :
| X | = | 21310241680 1286428979 |
