Work: Find the solution of equation 13.24x = （3.5+x）×8.97 .
Question type: Equation
Solution:Original question:
331 25 | x | = | ( | 7 2 | + | x | ) | × | 897 100 |
| Right side of the equation = | 7 2 | × | 897 100 | + | x | × | 897 100 |
| = | 6279 200 | + | x | × | 897 100 |
331 25 | x | = | 6279 200 | + | 897 100 | x |
Transposition :
331 25 | x | − | 897 100 | x | = | 6279 200 |
Combine the items on the left of the equation:
427 100 | x | = | 6279 200 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 6279 200 | ÷ | 427 100 |
| = | 6279 200 | × | 100 427 |
| = | 897 2 | × | 1 61 |
We obtained :
| x | = | 897 122 |
Convert the result to decimal form :
| x | = | 7.352459 |
