Work: Find the solution of equation 0.489 = -0.1895x+0.68 .
Question type: Equation
Solution:Original question:
489 1000 | = | - | 379 2000 | x | + | 17 25 |
Transposition :
379 2000 | x | = | 17 25 | − | 489 1000 |
Combine the items on the right of the equation:
379 2000 | x | = | 191 1000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 191 1000 | ÷ | 379 2000 |
| = | 191 1000 | × | 2000 379 |
| = | 191 | × | 2 379 |
We obtained :
| x | = | 382 379 |
Convert the result to decimal form :
| x | = | 1.007916 |
