Work: Find the solution of equation x2 = (0.2-x)0.00752 .
Question type: Equation
Solution:Original question:
| x | × | 2 | = | ( | 1 5 | − | x | ) | × | 47 6250 |
| Right side of the equation = | 1 5 | × | 47 6250 | − | x | × | 47 6250 |
| = | 47 31250 | − | x | × | 47 6250 |
| 2 | x | = | 47 31250 | − | 47 6250 | x |
Transposition :
| 2 | x | + | 47 6250 | x | = | 47 31250 |
Combine the items on the left of the equation:
12547 6250 | x | = | 47 31250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 47 31250 | ÷ | 12547 6250 |
| = | 47 31250 | × | 6250 12547 |
| = | 47 5 | × | 1 12547 |
We obtained :
| x | = | 47 62735 |
Convert the result to decimal form :
| x | = | 0.000749 |
