Work: Find the solution of equation 183.36+（7P-436.56-(7P*0.13-14-112)*0.1)*0.75 = 260 .
Question type: Equation
Solution:Original question:
4584 25 | + | ( | 7 | P | − | 10914 25 | − | ( | 7 | P | × | 13 100 | − | 14 | − | 112 | ) | × | 1 10 | ) | × | 3 4 | = | 260 |
| Left side of the equation = | 4584 25 | + | 7 | P | × | 3 4 | − | 10914 25 | × | 3 4 | − | ( | 7 | P | × | 13 100 | − | 14 | − | 112 | ) | × | 1 10 | × | 3 4 |
| = | 4584 25 | + | 21 4 | P | − | 16371 50 | − | ( | 7 | P | × | 13 100 | − | 14 | − | 112 | ) | × | 3 40 |
| = | - | 7203 50 | + | 21 4 | P | − | ( | 7 | P | × | 13 100 | − | 14 | − | 112 | ) | × | 3 40 |
| = | - | 7203 50 | + | 21 4 | P | − | 7 | P | × | 13 100 | × | 3 40 | + | 14 | × | 3 40 | + | 112 | × | 3 40 |
| = | - | 7203 50 | + | 21 4 | P | − | 273 4000 | P | + | 21 20 | + | 42 5 |
| = | - | 13461 100 | + | 20727 4000 | P |
| - | 13461 100 | + | 20727 4000 | P | = | 260 |
Transposition :
20727 4000 | P | = | 260 | + | 13461 100 |
Combine the items on the right of the equation:
20727 4000 | P | = | 39461 100 |
The coefficient of the unknown number is reduced to 1 :
| P | = | 39461 100 | ÷ | 20727 4000 |
| = | 39461 100 | × | 4000 20727 |
| = | 39461 | × | 40 20727 |
We obtained :
| P | = | 1578440 20727 |
Convert the result to decimal form :
| P | = | 76.153809 |
