[ 1/1 Equation]
Work: Find the solution of equation 142.85 = 60×X/(158.62+60-X) .
Question type: Equation
Solution:Original question:
2857 20 | = | 60 | X | ÷ | ( | 7931 50 | + | 60 | − | X | ) |
| Multiply both sides of the equation by: | ( | 7931 50 | + | 60 | − | X | ) |
2857 20 | ( | 7931 50 | + | 60 | − | X | ) | = | 60 | X |
2857 20 | × | 7931 50 | + | 2857 20 | × | 60 | − | 2857 20 | X | = | 60 | X |
22658867 1000 | + | 8571 | − | 2857 20 | X | = | 60 | X |
31229867 1000 | − | 2857 20 | X | = | 60 | X |
Transposition :
| - | 2857 20 | X | − | 60 | X | = | - | 31229867 1000 |
Combine the items on the left of the equation:
| - | 4057 20 | X | = | - | 31229867 1000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
31229867 1000 | = | 4057 20 | 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 :
4057 20 | X | = | 31229867 1000 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 31229867 1000 | ÷ | 4057 20 |
| = | 31229867 1000 | × | 20 4057 |
| = | 31229867 50 | × | 1 4057 |
We obtained :
| X | = | 31229867 202850 |
Convert the result to decimal form :
| X | = | 153.95547 |
