Work: Find the solution of equation y*（54.8+77.976+66.3）-（77.976+66.3）*759.2+66.3*1843.7+479.5*174.68/2+1294.8*72.41/2 = 0 .
Question type: Equation
Solution:Original question:
| y | ( | 274 5 | + | 9747 125 | + | 663 10 | ) | − | ( | 9747 125 | + | 663 10 | ) | × | 3796 5 | + | 663 10 | × | 18437 10 | + | 959 2 | × | 4367 25 | ÷ | 2 | + | 6474 5 | × | 7241 100 | ÷ | 2 | = | 0 |
| Left side of the equation = | y | ( | 274 5 | + | 9747 125 | + | 663 10 | ) | − | ( | 9747 125 | + | 663 10 | ) | × | 3796 5 | + | 12223731 100 | + | 4187953 100 | + | 23439117 500 |
| = | y | ( | 274 5 | + | 9747 125 | + | 663 10 | ) | − | ( | 9747 125 | + | 663 10 | ) | × | 3796 5 | + | 105497537 500 |
| y | ( | 274 5 | + | 9747 125 | + | 663 10 | ) | − | ( | 9747 125 | + | 663 10 | ) | × | 3796 5 | + | 105497537 500 | = | 0 |
| Left side of the equation = | y | × | 274 5 | + | y | × | 9747 125 | + | y | × | 663 10 | − | ( | 9747 125 | + | 663 10 | ) | × | 3796 5 | + | 105497537 500 |
| = | 49769 250 | y | − | ( | 9747 125 | + | 663 10 | ) | × | 3796 5 | + | 105497537 500 |
| = | 49769 250 | y | − | 9747 125 | × | 3796 5 | − | 663 10 | × | 3796 5 | + | 105497537 500 |
| = | 49769 250 | y | − | 36999612 625 | − | 1258374 25 | + | 105497537 500 |
y≈-509.658295 , keep 6 decimal places
