Work: Find the solution of equation (4.7547+x)/(7.3078+x) = 0.63306 .
Question type: Equation
Solution:Original question:
| ( | 47547 10000 | + | x | ) | ÷ | ( | 36539 5000 | + | x | ) | = | 31653 50000 |
| Multiply both sides of the equation by: | ( | 36539 5000 | + | x | ) |
| ( | 47547 10000 | + | x | ) | = | 31653 50000 | ( | 36539 5000 | + | x | ) |
47547 10000 | + | x | = | 31653 50000 | ( | 36539 5000 | + | x | ) |
47547 10000 | + | x | = | 31653 50000 | × | 36539 5000 | + | 31653 50000 | x |
47547 10000 | + | x | = | 1156568967 250000000 | + | 31653 50000 | x |
Transposition :
| x | − | 31653 50000 | x | = | 1156568967 250000000 | − | 47547 10000 |
Combine the items on the left of the equation:
18347 50000 | x | = | 1156568967 250000000 | − | 47547 10000 |
x≈-0.349987 , keep 6 decimal places
