Work: Find the solution of equation 28*x+3 = 9 .
Question type: Equation
Solution:Original question:
| 28 | x | + | 3 | = | 9 |
Transposition :
| 28 | x | = | 9 | − | 3 |
Combine the items on the right of the equation:
| 28 | x | = | 6 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 6 | ÷ | 28 |
| = | 6 | × | 1 28 |
| = | 3 | × | 1 14 |
We obtained :
| x | = | 3 14 |
Convert the result to decimal form :
| x | = | 0.214286 |
