Work: Find the solution of equation 1.603*(f+f-0.94)+0.399*(f-0.94+f-7.59)+6.060*(f-7.59+f-11.05) = 6*140*195*2/1000 .
Question type: Equation
Solution:Original question:
1603 1000 | ( | f | + | f | − | 47 50 | ) | + | 399 1000 | ( | f | − | 47 50 | + | f | − | 759 100 | ) | + | 303 50 | ( | f | − | 759 100 | + | f | − | 221 20 | ) | = | 6 | × | 140 | × | 195 | × | 2 | ÷ | 1000 |
| Left side of the equation = | 1603 1000 | f | + | 1603 1000 | f | − | 1603 1000 | × | 47 50 | + | 399 1000 | ( | f | − | 47 50 | + | f | − | 759 100 | ) | + | 303 50 | ( | f | − | 759 100 | + | f | − | 221 20 | ) |
| = | 1603 1000 | f | + | 1603 1000 | f | − | 75341 50000 | + | 399 1000 | ( | f | − | 47 50 | + | f | − | 759 100 | ) | + | 303 50 | ( | f | − | 759 100 | + | f | − | 221 20 | ) |
| = | 1603 500 | f | − | 75341 50000 | + | 399 1000 | ( | f | − | 47 50 | + | f | − | 759 100 | ) | + | 303 50 | ( | f | − | 759 100 | + | f | − | 221 20 | ) |
| = | 1603 500 | f | − | 75341 50000 | + | 399 1000 | f | − | 399 1000 | × | 47 50 | + | 399 1000 | f | − | 399 1000 | × | 759 100 | + | 303 50 |
| = | 1603 500 | f | − | 75341 50000 | + | 399 1000 | f | − | 18753 50000 | + | 399 1000 | f | − | 302841 100000 | + | 303 50 | ( | f | − | 759 100 | + | f | − | 221 20 | ) |
f≈27.627679 , keep 6 decimal places
