Work: Find the solution of equation (3323+200x)*150+7（36-x） = 0 .
Question type: Equation
Solution:Original question:
| ( | 3323 | + | 200 | x | ) | × | 150 | + | 7 | ( | 36 | − | x | ) | = | 0 |
| Left side of the equation = | 3323 | × | 150 | + | 200 | x | × | 150 | + | 7 | ( | 36 | − | x | ) |
| = | 498450 | + | 30000 | x | + | 7 | ( | 36 | − | x | ) |
| = | 498450 | + | 30000 | x | + | 7 | × | 36 | − | 7 | x |
| = | 498450 | + | 30000 | x | + | 252 | − | 7 | x |
| = | 498702 | + | 29993 | x |
| 498702 | + | 29993 | x | = | 0 |
Transposition :
| 29993 | x | = | 0 | − | 498702 |
Combine the items on the right of the equation:
| 29993 | x | = | - | 498702 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 498702 | ÷ | 29993 |
| = | - | 498702 | × | 1 29993 |
We obtained :
| x | = | - | 498702 29993 |
Convert the result to decimal form :
| x | = | - 16.62728 |
