[ 1/1 Equation]
Work: Find the solution of equation x*403.3+(6.5-x)*424.3 = 6143.15+217.9*6.5*10 .
Question type: Equation
Solution:Original question:
| x | × | 4033 10 | + | ( | 13 2 | − | x | ) | × | 4243 10 | = | 122863 20 | + | 2179 10 | × | 13 2 | × | 10 |
| Left side of the equation = | 4033 10 | x | + | 13 2 | × | 4243 10 | − | x | × | 4243 10 |
| = | 4033 10 | x | + | 55159 20 | − | x | × | 4243 10 |
| = | - | 21 | x | + | 55159 20 |
| - | 21 | x | + | 55159 20 | = | 122863 20 | + | 2179 10 | × | 13 2 | × | 10 |
| Right side of the equation = | 122863 20 | + | 28327 2 |
| = | 406133 20 |
| - | 21 | x | + | 55159 20 | = | 406133 20 |
Transposition :
| - | 21 | x | = | 406133 20 | − | 55159 20 |
Combine the items on the right of the equation:
| - | 21 | x | = | 175487 10 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 175487 10 | = | 21 | 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 :
| 21 | x | = | - | 175487 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 175487 10 | ÷ | 21 |
| = | - | 175487 10 | × | 1 21 |
We obtained :
| x | = | - | 175487 210 |
Convert the result to decimal form :
| x | = | - 835.652381 |
