Work: Find the solution of equation 13x = （3.5+x）×7.96 .
Question type: Equation
Solution:Original question:
| 13 | x | = | ( | 7 2 | + | x | ) | × | 199 25 |
| Right side of the equation = | 7 2 | × | 199 25 | + | x | × | 199 25 |
| = | 1393 50 | + | x | × | 199 25 |
| 13 | x | = | 1393 50 | + | 199 25 | x |
Transposition :
| 13 | x | − | 199 25 | x | = | 1393 50 |
Combine the items on the left of the equation:
126 25 | x | = | 1393 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1393 50 | ÷ | 126 25 |
| = | 1393 50 | × | 25 126 |
| = | 199 2 | × | 1 18 |
We obtained :
| x | = | 199 36 |
Convert the result to decimal form :
| x | = | 5.527778 |
