Work: Find the solution of equation 0.813*(f+f-0.48)+1.341*(f-0.48+f-11.57)+6.060*(f-11.57+f-15.00) = 6*140*195*2/1000 .
Question type: Equation
Solution:Original question:
813 1000 | ( | f | + | f | − | 12 25 | ) | + | 1341 1000 | ( | f | − | 12 25 | + | f | − | 1157 100 | ) | + | 303 50 | ( | f | − | 1157 100 | + | f | − | 15 | ) | = | 6 | × | 140 | × | 195 | × | 2 | ÷ | 1000 |
| Left side of the equation = | 813 1000 | f | + | 813 1000 | f | − | 813 1000 | × | 12 25 | + | 1341 1000 | ( | f | − | 12 25 | + | f | − | 1157 100 | ) | + | 303 50 | ( | f | − | 1157 100 | + | f | − | 15 | ) |
| = | 813 1000 | f | + | 813 1000 | f | − | 2439 6250 | + | 1341 1000 | ( | f | − | 12 25 | + | f | − | 1157 100 | ) | + | 303 50 | ( | f | − | 1157 100 | + | f | − | 15 | ) |
| = | 813 500 | f | − | 2439 6250 | + | 1341 1000 | ( | f | − | 12 25 | + | f | − | 1157 100 | ) | + | 303 50 | ( | f | − | 1157 100 | + | f | − | 15 | ) |
| = | 813 500 | f | − | 2439 6250 | + | 1341 1000 | f | − | 1341 1000 | × | 12 25 | + | 1341 1000 | f | − | 1341 1000 | × | 1157 100 | + | 303 50 |
| = | 813 500 | f | − | 2439 6250 | + | 1341 1000 | f | − | 4023 6250 | + | 1341 1000 | f | − | 1551537 100000 | + | 303 50 | ( | f | − | 1157 100 | + | f | − | 15 | ) |
| = | 1077 250 | f | − | 1654929 100000 | + | 303 50 | ( | f | − | 1157 100 | + | f | − | 15 | ) |
| = | 1077 250 | f | − | 1654929 100000 | + | 303 50 | f | − | 303 50 | × | 1157 100 | + | 303 50 | f | − | 303 50 | × | 15 |
| = | 1077 250 | f | − | 1654929 100000 | + | 303 50 | f | − | 350571 5000 | + | 303 50 | f | − | 909 10 |
f≈30.750152 , keep 6 decimal places
