Question type: Equation
Solution:Original question:
134 5 | × | 2 5 | × | 41 50 | × | 67 10 | − | 1419 50 | − | 147 5 | = | x | × | 2 5 | × | 41 50 | × | 67 10 | − | 2023 100 | − | 141 5 | − | 2023 100 |
| Left side of the equation = | 184049 3125 | − | 1419 50 | − | 147 5 |
| = | 6973 6250 |
6973 6250 | = | x | × | 2 5 | × | 41 50 | × | 67 10 | − | 2023 100 | − | 141 5 | − | 2023 100 |
| Right side of the equation = | x | × | 2747 1250 | − | 2023 100 | − | 141 5 | − | 2023 100 |
| = | 2747 1250 | x | − | 3433 50 |
6973 6250 | = | 2747 1250 | x | − | 3433 50 |
Transposition :
| - | 2747 1250 | x | = | - | 3433 50 | − | 6973 6250 |
Combine the items on the right of the equation:
| - | 2747 1250 | x | = | - | 218049 3125 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
218049 3125 | = | 2747 1250 | 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 :
2747 1250 | x | = | 218049 3125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 218049 3125 | ÷ | 2747 1250 |
| = | 218049 3125 | × | 1250 2747 |
| = | 218049 5 | × | 2 2747 |
We obtained :
| x | = | 436098 13735 |
Convert the result to decimal form :
| x | = | 31.750855 |
