Work: Find the solution of equation 222 = x*395.6/0.2826+0.8*（1-x）*120 .
Question type: Equation
Solution:Original question:
| 222 | = | x | × | 1978 5 | ÷ | 1413 5000 | + | 4 5 | ( | 1 | − | x | ) | × | 120 |
| Right side of the equation = | x | × | 1978000 1413 | + | 96 | ( | 1 | − | x | ) |
| 222 | = | 1978000 1413 | x | + | 96 | ( | 1 | − | x | ) |
| Right side of the equation = | 1978000 1413 | x | + | 96 | × | 1 | − | 96 | x |
| = | 1978000 1413 | x | + | 96 | − | 96 | x |
| = | 1842352 1413 | x | + | 96 |
| 222 | = | 1842352 1413 | x | + | 96 |
Transposition :
| - | 1842352 1413 | x | = | 96 | − | 222 |
Combine the items on the right of the equation:
| - | 1842352 1413 | x | = | - | 126 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 126 | = | 1842352 1413 | 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 :
1842352 1413 | x | = | 126 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 126 | ÷ | 1842352 1413 |
| = | 126 | × | 1413 1842352 |
| = | 63 | × | 1413 921176 |
We obtained :
| x | = | 89019 921176 |
Convert the result to decimal form :
| x | = | 0.096636 |
