Work: Find the solution of equation （93474-1.5X）*9.2/20.8*0.9 = 16802+7X .
Question type: Equation
Solution:Original question:
| ( | 93474 | − | 3 2 | X | ) | × | 46 5 | ÷ | 104 5 | × | 9 10 | = | 16802 | + | 7 | X |
| Left side of the equation = | ( | 93474 | − | 3 2 | X | ) | × | 207 520 |
| ( | 93474 | − | 3 2 | X | ) | × | 207 520 | = | 16802 | + | 7 | X |
| Left side of the equation = | 93474 | × | 207 520 | − | 3 2 | X | × | 207 520 |
| = | 9674559 260 | − | 621 1040 | X |
9674559 260 | − | 621 1040 | X | = | 16802 | + | 7 | X |
Transposition :
| - | 621 1040 | X | − | 7 | X | = | 16802 | − | 9674559 260 |
Combine the items on the left of the equation:
| - | 7901 1040 | X | = | 16802 | − | 9674559 260 |
Combine the items on the right of the equation:
| - | 7901 1040 | X | = | - | 5306039 260 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
5306039 260 | = | 7901 1040 | 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 :
7901 1040 | X | = | 5306039 260 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 5306039 260 | ÷ | 7901 1040 |
| = | 5306039 260 | × | 1040 7901 |
| = | 5306039 | × | 4 7901 |
We obtained :
| X | = | 21224156 7901 |
Convert the result to decimal form :
| X | = | 2686.261992 |
