Work: Find the solution of equation （0.795+1.57x）*（x-0.508） = 1680 .
Question type: Equation
Solution:Original question:
| ( | 159 200 | + | 157 100 | x | ) | ( | x | − | 127 250 | ) | = | 1680 |
| Left side of the equation = | 159 200 | ( | x | − | 127 250 | ) | + | 157 100 | x | ( | x | − | 127 250 | ) |
| = | 159 200 | x | − | 159 200 | × | 127 250 | + | 157 100 | x | ( | x | − | 127 250 | ) |
| = | 159 200 | x | − | 20193 50000 | + | 157 100 | x | ( | x | − | 127 250 | ) |
| = | 159 200 | x | − | 20193 50000 | + | 157 100 | x | x | − | 157 100 | x | × | 127 250 |
| = | 159 200 | x | − | 20193 50000 | + | 157 100 | x | x | − | 19939 25000 | x |
| = | - | 8 3125 | x | − | 20193 50000 | + | 157 100 | x | x |
| - | 8 3125 | x | − | 20193 50000 | + | 157 100 | x | x | = | 1680 |
The solution of the equation:
x1≈-32.714944 , keep 6 decimal places
x2≈32.716575 , keep 6 decimal places
There are 2 solution(s).
