[ 1/1 Equation]
Work: Find the solution of equation 13x-6.8+1.8x = 56.8 .
Question type: Equation
Solution:Original question:
| 13 | x | − | 34 5 | + | 9 5 | x | = | 284 5 |
| Left side of the equation = | 74 5 | x | − | 34 5 |
74 5 | x | − | 34 5 | = | 284 5 |
Transposition :
74 5 | x | = | 284 5 | + | 34 5 |
Combine the items on the right of the equation:
74 5 | x | = | 318 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 318 5 | ÷ | 74 5 |
| = | 318 5 | × | 5 74 |
| = | 159 | × | 1 37 |
We obtained :
| x | = | 159 37 |
Convert the result to decimal form :
| x | = | 4.297297 |
