Work: Find the solution of equation -18.34+1.498x+0.001377x2 = 692.86 .
Question type: Equation
Solution:Original question:
| - | 917 50 | + | 749 500 | x | + | 1377 1000000 | x | × | 2 | = | 34643 50 |
| Left side of the equation = | - | 917 50 | + | 749 500 | x | + | 1377 500000 | x |
| = | - | 917 50 | + | 750377 500000 | x |
| - | 917 50 | + | 750377 500000 | x | = | 34643 50 |
Transposition :
750377 500000 | x | = | 34643 50 | + | 917 50 |
Combine the items on the right of the equation:
750377 500000 | x | = | 3556 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3556 5 | ÷ | 750377 500000 |
| = | 3556 5 | × | 500000 750377 |
| = | 3556 | × | 100000 750377 |
We obtained :
| x | = | 355600000 750377 |
Convert the result to decimal form :
| x | = | 473.895122 |
