Work: Find the solution of equation 4.90 = 1.0x14.3x103x1.0X（0.075-0.5X） .
Question type: Equation
Solution:Original question:
49 10 | = | 1 | x | × | 143 10 | x | × | 103 | x | × | 1 | x | ( | 3 40 | − | 1 2 | x | ) |
| Right side of the equation = | 14729 10 | x | x | x | x | ( | 3 40 | − | 1 2 | x | ) |
49 10 | = | 14729 10 | x | x | x | x | ( | 3 40 | − | 1 2 | x | ) |
| Right side of the equation = | 14729 10 | x | x | x | x | × | 3 40 | − | 14729 10 | x | x | x | x | × | 1 2 |
| = | 44187 400 | x | x | x | x | − | 14729 20 | x | x | x | x | x |
49 10 | = | 44187 400 | x | x | x | x | − | 14729 20 | x | x | x | x | x |
the solutions is:
x≈-0.341160 , keep 6 decimal places
There are 1 solution(s).
