Work: Find the solution of equation 12.1x = （3.5+x）×7.97 .
Question type: Equation
Solution:Original question:
121 10 | x | = | ( | 7 2 | + | x | ) | × | 797 100 |
| Right side of the equation = | 7 2 | × | 797 100 | + | x | × | 797 100 |
| = | 5579 200 | + | x | × | 797 100 |
121 10 | x | = | 5579 200 | + | 797 100 | x |
Transposition :
121 10 | x | − | 797 100 | x | = | 5579 200 |
Combine the items on the left of the equation:
413 100 | x | = | 5579 200 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 5579 200 | ÷ | 413 100 |
| = | 5579 200 | × | 100 413 |
| = | 797 2 | × | 1 59 |
We obtained :
| x | = | 797 118 |
Convert the result to decimal form :
| x | = | 6.754237 |
