Work: Find the solution of equation 0.3418*x+54.98*x+55.98*x-80 = 0 .
Question type: Equation
Solution:Original question:
1709 5000 | x | + | 2749 50 | x | + | 2799 50 | x | − | 80 | = | 0 |
| Left side of the equation = | 556509 5000 | x | − | 80 |
556509 5000 | x | − | 80 | = | 0 |
Transposition :
556509 5000 | x | = | 0 | + | 80 |
Combine the items on the right of the equation:
556509 5000 | x | = | 80 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 80 | ÷ | 556509 5000 |
| = | 80 | × | 5000 556509 |
We obtained :
| x | = | 400000 556509 |
Convert the result to decimal form :
| x | = | 0.718766 |
