[ 1/1 Equation]
Work: Find the solution of equation (0.000418+0.85856*x)/(1+0.0851*x) = 0.79184 .
Question type: Equation
Solution:Original question:
| ( | 209 500000 | + | 2683 3125 | x | ) | ÷ | ( | 1 | + | 851 10000 | x | ) | = | 4949 6250 |
| Multiply both sides of the equation by: | ( | 1 | + | 851 10000 | x | ) |
| ( | 209 500000 | + | 2683 3125 | x | ) | = | 4949 6250 | ( | 1 | + | 851 10000 | x | ) |
209 500000 | + | 2683 3125 | x | = | 4949 6250 | ( | 1 | + | 851 10000 | x | ) |
209 500000 | + | 2683 3125 | x | = | 4949 6250 | × | 1 | + | 4949 6250 | × | 851 10000 | x |
209 500000 | + | 2683 3125 | x | = | 4949 6250 | + | 4211599 62500000 | x |
Transposition :
2683 3125 | x | − | 4211599 62500000 | x | = | 4949 6250 | − | 209 500000 |
After the equation is converted into a general formula, there is a common factor:
( x - 1 )
From
x - 1 = 0
it is concluded that:：
| x1=1 | , it is the incremental root of the eqution. |
Solutions that cannot be obtained by factorization:
x2≈-11.750881 , keep 6 decimal places
There are 2 solution(s).
There is(are) 1 additive root(s) and 1 real solutions.(Note:additive root, generated by computer, but not suitable for this equation.)
