Work: Find the solution of equation 0.2*285.8+x*282.9 = 113.74 .
Question type: Equation
Solution:Original question:
1 5 | × | 1429 5 | + | x | × | 2829 10 | = | 5687 50 |
| Left side of the equation = | 1429 25 | + | x | × | 2829 10 |
1429 25 | + | 2829 10 | x | = | 5687 50 |
Transposition :
2829 10 | x | = | 5687 50 | − | 1429 25 |
Combine the items on the right of the equation:
2829 10 | x | = | 2829 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2829 50 | ÷ | 2829 10 |
| = | 2829 50 | × | 10 2829 |
| = | 1 5 | × | 1 |
We obtained :
| x | = | 1 5 |
Convert the result to decimal form :
| x | = | 0.2 |
