Work: Find the solution of equation 5 = -0.38x+3.21 .
Question type: Equation
Solution:Original question:
| 5 | = | - | 19 50 | x | + | 321 100 |
Transposition :
19 50 | x | = | 321 100 | − | 5 |
Combine the items on the right of the equation:
19 50 | x | = | - | 179 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 179 100 | ÷ | 19 50 |
| = | - | 179 100 | × | 50 19 |
| = | - | 179 2 | × | 1 19 |
We obtained :
| x | = | - | 179 38 |
Convert the result to decimal form :
| x | = | - 4.710526 |
