Work: Find the solution of equation 0.8 = (6.799-x)/6.799 .
Question type: Equation
Solution:Original question:
4 5 | = | ( | 6799 1000 | − | x | ) | ÷ | 6799 1000 |
| Right side of the equation = | 6799 1000 | × | 1000 6799 | − | x | × | 1000 6799 |
| = | 1 | − | x | × | 1000 6799 |
4 5 | = | 1 | − | 1000 6799 | x |
Transposition :
1000 6799 | x | = | 1 | − | 4 5 |
Combine the items on the right of the equation:
1000 6799 | x | = | 1 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1 5 | ÷ | 1000 6799 |
| = | 1 5 | × | 6799 1000 |
We obtained :
| x | = | 6799 5000 |
Convert the result to decimal form :
| x | = | 1.3598 |
