Work: Find the solution of equation 120.12+18x = 0.1206*(979.09+18x) .
Question type: Equation
Solution:Original question:
3003 25 | + | 18 | x | = | 603 5000 | ( | 97909 100 | + | 18 | x | ) |
| Right side of the equation = | 603 5000 | × | 97909 100 | + | 603 5000 | × | 18 | x |
| = | 59039127 500000 | + | 5427 2500 | x |
3003 25 | + | 18 | x | = | 59039127 500000 | + | 5427 2500 | x |
Transposition :
| 18 | x | − | 5427 2500 | x | = | 59039127 500000 | − | 3003 25 |
Combine the items on the left of the equation:
39573 2500 | x | = | 59039127 500000 | − | 3003 25 |
Combine the items on the right of the equation:
39573 2500 | x | = | - | 1020873 500000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 1020873 500000 | ÷ | 39573 2500 |
| = | - | 1020873 500000 | × | 2500 39573 |
| = | - | 340291 200 | × | 1 13191 |
We obtained :
| x | = | - | 340291 2638200 |
Convert the result to decimal form :
| x | = | - 0.128986 |
