Work: Find the solution of equation 0.353*(f+f-0.21)+0.399*(f-0.21+f-5.59)+7.310*(f-5.59+f-9.79) = 6*140*195*2/1000 .
Question type: Equation
Solution:Original question:
353 1000 | ( | f | + | f | − | 21 100 | ) | + | 399 1000 | ( | f | − | 21 100 | + | f | − | 559 100 | ) | + | 731 100 | ( | f | − | 559 100 | + | f | − | 979 100 | ) | = | 6 | × | 140 | × | 195 | × | 2 | ÷ | 1000 |
| Left side of the equation = | 353 1000 | f | + | 353 1000 | f | − | 353 1000 | × | 21 100 | + | 399 1000 | ( | f | − | 21 100 | + | f | − | 559 100 | ) | + | 731 100 | ( | f | − | 559 100 | + | f | − | 979 100 | ) |
| = | 353 1000 | f | + | 353 1000 | f | − | 7413 100000 | + | 399 1000 | ( | f | − | 21 100 | + | f | − | 559 100 | ) | + | 731 100 | ( | f | − | 559 100 | + | f | − | 979 100 | ) |
| = | 353 500 | f | − | 7413 100000 | + | 399 1000 | ( | f | − | 21 100 | + | f | − | 559 100 | ) | + | 731 100 | ( | f | − | 559 100 | + | f | − | 979 100 | ) |
| = | 353 500 | f | − | 7413 100000 | + | 399 1000 | f | − | 399 1000 | × | 21 100 | + | 399 1000 | f | − | 399 1000 | × | 559 100 | + | 731 100 |
| = | 353 500 | f | − | 7413 100000 | + | 399 1000 | f | − | 8379 100000 | + | 399 1000 | f | − | 223041 100000 | + | 731 100 | ( | f | − | 559 100 | + | f | − | 979 100 | ) |
| = | 188 125 | f | − | 238833 100000 | + | 731 100 | ( | f | − | 559 100 | + | f | − | 979 100 | ) |
| = | 188 125 | f | − | 238833 100000 | + | 731 100 | f | − | 731 100 | × | 559 100 | + | 731 100 | f | − | 731 100 | × | 979 100 |
| = | 188 125 | f | − | 238833 100000 | + | 731 100 | f | − | 408629 10000 | + | 731 100 | f | − | 715649 10000 |
f≈27.438361 , keep 6 decimal places
