Work: Find the solution of equation 3.3/(75+x)x = 1.248 .
Question type: Equation
Solution:Original question:
33 10 | ÷ | ( | 75 | + | x | ) | × | x | = | 156 125 |
| Multiply both sides of the equation by: | ( | 75 | + | x | ) |
33 10 | x | = | 156 125 | ( | 75 | + | x | ) |
33 10 | x | = | 156 125 | × | 75 | + | 156 125 | x |
33 10 | x | = | 468 5 | + | 156 125 | x |
Transposition :
33 10 | x | − | 156 125 | x | = | 468 5 |
Combine the items on the left of the equation:
513 250 | x | = | 468 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 468 5 | ÷ | 513 250 |
| = | 468 5 | × | 250 513 |
| = | 52 | × | 50 57 |
We obtained :
| x | = | 2600 57 |
Convert the result to decimal form :
| x | = | 45.614035 |
