Work: Find the solution of equation 290.09+75+（60*P-2184.4）*（1-25%） = 485.02 .
Question type: Equation
Solution:Original question:
29009 100 | + | 75 | + | ( | 60 | P | − | 10922 5 | ) | ( | 1 | − | 25 100 | ) | = | 24251 50 |
| Left side of the equation = | 36509 100 | + | ( | 60 | P | − | 10922 5 | ) | ( | 1 | − | 25 100 | ) |
36509 100 | + | ( | 60 | P | − | 10922 5 | ) | ( | 1 | − | 25 100 | ) | = | 24251 50 |
| Left side of the equation = | 36509 100 | + | 60 | P | ( | 1 | − | 25 100 | ) | − | 10922 5 | ( | 1 | − | 25 100 | ) |
| = | 36509 100 | + | 60 | P | × | 1 | − | 60 | P | × | 25 100 | − | 10922 5 | ( | 1 | − | 25 100 | ) |
| = | 36509 100 | + | 60 | P | − | 15 | P | − | 10922 5 | ( | 1 | − | 25 100 | ) |
| = | 36509 100 | + | 45 | P | − | 10922 5 | ( | 1 | − | 25 100 | ) |
| = | 36509 100 | + | 45 | P | − | 10922 5 | × | 1 | + | 10922 5 | × | 25 100 |
| = | 36509 100 | + | 45 | P | − | 10922 5 | + | 5461 10 |
| = | - | 127321 100 | + | 45 | P |
| - | 127321 100 | + | 45 | P | = | 24251 50 |
Transposition :
| 45 | P | = | 24251 50 | + | 127321 100 |
Combine the items on the right of the equation:
| 45 | P | = | 175823 100 |
The coefficient of the unknown number is reduced to 1 :
| P | = | 175823 100 | ÷ | 45 |
| = | 175823 100 | × | 1 45 |
We obtained :
| P | = | 175823 4500 |
Convert the result to decimal form :
| P | = | 39.071778 |
