Work: Find the solution of equation 37.42（1-x） = 25.31 .
Question type: Equation
Solution:Original question:
1871 50 | ( | 1 | − | x | ) | = | 2531 100 |
| Left side of the equation = | 1871 50 | × | 1 | − | 1871 50 | x |
| = | 1871 50 | − | 1871 50 | x |
1871 50 | − | 1871 50 | x | = | 2531 100 |
Transposition :
| - | 1871 50 | x | = | 2531 100 | − | 1871 50 |
Combine the items on the right of the equation:
| - | 1871 50 | x | = | - | 1211 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1211 100 | = | 1871 50 | 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 :
1871 50 | x | = | 1211 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1211 100 | ÷ | 1871 50 |
| = | 1211 100 | × | 50 1871 |
| = | 1211 2 | × | 1 1871 |
We obtained :
| x | = | 1211 3742 |
Convert the result to decimal form :
| x | = | 0.323624 |
