Work: Find the solution of equation 0.256a*3204+0.221a*6480+0.203a*11052+0.168a*12852+0.152a*11184 = 446275 .
Question type: Equation
Solution:Original question:
32 125 | a | × | 3204 | + | 221 1000 | a | × | 6480 | + | 203 1000 | a | × | 11052 | + | 21 125 | a | × | 12852 | = | 446275 |
| Left side of the equation = | 102528 125 | a | + | 35802 25 | a | + | 560889 250 | a | + | 269892 125 | a | + | 212496 125 | a |
| = | 2088741 250 | a |
2088741 250 | a | = | 446275 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 446275 | ÷ | 2088741 250 |
| = | 446275 | × | 250 2088741 |
We obtained :
| a | = | 111568750 2088741 |
Convert the result to decimal form :
| a | = | 53.414353 |
