Work: Find the solution of equation 0.85*41x+0.15*15x = 12576 .
Question type: Equation
Solution:Original question:
17 20 | × | 41 | x | + | 3 20 | × | 15 | x | = | 12576 |
| Left side of the equation = | 697 20 | x | + | 9 4 | x |
| = | 371 10 | x |
371 10 | x | = | 12576 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 12576 | ÷ | 371 10 |
| = | 12576 | × | 10 371 |
We obtained :
| x | = | 125760 371 |
Convert the result to decimal form :
| x | = | 338.975741 |
