Work: Find the solution of equation 4x＋1.2×5 = 24.4 .
Question type: Equation
Solution:Original question:
| 4 | x | + | 6 5 | × | 5 | = | 122 5 |
| Left side of the equation = | 4 | x | + | 6 |
| 4 | x | + | 6 | = | 122 5 |
Transposition :
| 4 | x | = | 122 5 | − | 6 |
Combine the items on the right of the equation:
| 4 | x | = | 92 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 92 5 | ÷ | 4 |
| = | 92 5 | × | 1 4 |
| = | 23 5 | × | 1 |
We obtained :
| x | = | 23 5 |
Convert the result to decimal form :
| x | = | 4.6 |
