Work: Find the solution of equation 879+x/1.17*17%+x*0.05+x*30% = 0 .
Question type: Equation
Solution:Original question:
| 879 | + | x | ÷ | 117 100 | × | 17 100 | + | x | × | 1 20 | + | x | × | 30 100 | = | 0 |
| Left side of the equation = | 879 | + | x | × | 17 117 | + | x | × | 1 20 | + | x | × | 30 100 |
| = | 879 | + | 1159 2340 | x |
| 879 | + | 1159 2340 | x | = | 0 |
Transposition :
1159 2340 | x | = | 0 | − | 879 |
Combine the items on the right of the equation:
1159 2340 | x | = | - | 879 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 879 | ÷ | 1159 2340 |
| = | - | 879 | × | 2340 1159 |
We obtained :
| x | = | - | 2056860 1159 |
Convert the result to decimal form :
| x | = | - 1774.685073 |
