☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation x/(106.8+x) = 0.4 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | 534 5 | + | x | ) | = | 2 5 |
| Multiply both sides of the equation by: | ( | 534 5 | + | x | ) |
| x | = | 2 5 | ( | 534 5 | + | x | ) |
| x | = | 2 5 | × | 534 5 | + | 2 5 | x |
| x | = | 1068 25 | + | 2 5 | x |
Transposition :
| x | − | 2 5 | x | = | 1068 25 |
Combine the items on the left of the equation:
3 5 | x | = | 1068 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1068 25 | ÷ | 3 5 |
| = | 1068 25 | × | 5 3 |
| = | 356 5 | × | 1 |
We obtained :
| x | = | 356 5 |
Convert the result to decimal form :
| x | = | 71.2 |
