Work: Find the solution of equation （80263-1.5X）*10.4/22.4*0.9 = 19117+8X .
Question type: Equation
Solution:Original question:
| ( | 80263 | − | 3 2 | X | ) | × | 52 5 | ÷ | 112 5 | × | 9 10 | = | 19117 | + | 8 | X |
| Left side of the equation = | ( | 80263 | − | 3 2 | X | ) | × | 117 280 |
| ( | 80263 | − | 3 2 | X | ) | × | 117 280 | = | 19117 | + | 8 | X |
| Left side of the equation = | 80263 | × | 117 280 | − | 3 2 | X | × | 117 280 |
| = | 9390771 280 | − | 351 560 | X |
9390771 280 | − | 351 560 | X | = | 19117 | + | 8 | X |
Transposition :
| - | 351 560 | X | − | 8 | X | = | 19117 | − | 9390771 280 |
Combine the items on the left of the equation:
| - | 4831 560 | X | = | 19117 | − | 9390771 280 |
Combine the items on the right of the equation:
| - | 4831 560 | X | = | - | 4038011 280 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
4038011 280 | = | 4831 560 | 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 :
4831 560 | X | = | 4038011 280 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 4038011 280 | ÷ | 4831 560 |
| = | 4038011 280 | × | 560 4831 |
| = | 4038011 | × | 2 4831 |
We obtained :
| X | = | 8076022 4831 |
Convert the result to decimal form :
| X | = | 1671.708135 |
