Work: Find the solution of equation 30/（14.3*200） = x（395-x/2） .
Question type: Equation
Solution:Original question:
| 30 | ÷ | ( | 143 10 | × | 200 | ) | = | x | ( | 395 | − | x | ÷ | 2 | ) |
| Multiply both sides of the equation by: | ( | 143 10 | × | 200 | ) |
| 30 | = | x | ( | 395 | − | x | ÷ | 2 | ) | ( | 143 10 | × | 200 | ) |
| 30 | = | x | × | 395 | ( | 143 10 | × | 200 | ) | − | x | x | ÷ | 2 | × | ( | 143 10 | × | 200 | ) |
| 30 | = | x | × | 395 | × | 143 10 | × | 200 | − | x | x | × | 1 2 | ( | 143 10 | × | 200 | ) |
| 30 | = | x | × | 1129700 | − | x | x | × | 1 2 | ( | 143 10 | × | 200 | ) |
| 30 | = | 1129700 | x | − | x | x | × | 1 2 | × | 143 10 | × | 200 |
| 30 | = | 1129700 | x | − | x | x | × | 1430 |
x=0, it is the incremental root of the eqution.
There are 1 solution(s).
There is(are) 1 additive root(s) and 0 real solutions.(Note:additive root, generated by computer, but not suitable for this equation.)
