Work: Find the solution of equation （100-69+x/4*0.2）*3.1699-x = 0 .
Question type: Equation
Solution:Original question:
| ( | 100 | − | 69 | + | x | ÷ | 4 | × | 1 5 | ) | × | 31699 10000 | − | x | = | 0 |
| Left side of the equation = | 100 | × | 31699 10000 | − | 69 | × | 31699 10000 | + | x | ÷ | 4 | × | 1 5 | × | 31699 10000 | − | x |
| = | 31699 100 | − | 2187231 10000 | + | x | × | 31699 200000 | − | x |
| = | 982669 10000 | − | 168301 200000 | x |
982669 10000 | − | 168301 200000 | x | = | 0 |
Transposition :
| - | 168301 200000 | x | = | 0 | − | 982669 10000 |
Combine the items on the right of the equation:
| - | 168301 200000 | x | = | - | 982669 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
982669 10000 | = | 168301 200000 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
168301 200000 | x | = | 982669 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 982669 10000 | ÷ | 168301 200000 |
| = | 982669 10000 | × | 200000 168301 |
| = | 982669 | × | 20 168301 |
We obtained :
| x | = | 19653380 168301 |
Convert the result to decimal form :
| x | = | 116.775183 |
