Work: Find the solution of equation 12.09x = （3.5+x）×8.98 .
Question type: Equation
Solution:Original question:
1209 100 | x | = | ( | 7 2 | + | x | ) | × | 449 50 |
| Right side of the equation = | 7 2 | × | 449 50 | + | x | × | 449 50 |
| = | 3143 100 | + | x | × | 449 50 |
1209 100 | x | = | 3143 100 | + | 449 50 | x |
Transposition :
1209 100 | x | − | 449 50 | x | = | 3143 100 |
Combine the items on the left of the equation:
311 100 | x | = | 3143 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3143 100 | ÷ | 311 100 |
| = | 3143 100 | × | 100 311 |
| = | 3143 | × | 1 311 |
We obtained :
| x | = | 3143 311 |
Convert the result to decimal form :
| x | = | 10.106109 |
