Work: Find the solution of equation 0.85*45X+0.15*20X = 18500*0.53 .
Question type: Equation
Solution:Original question:
17 20 | × | 45 | X | + | 3 20 | × | 20 | X | = | 18500 | × | 53 100 |
| Left side of the equation = | 153 4 | X | + | 3 | X |
| = | 165 4 | X |
165 4 | X | = | 18500 | × | 53 100 |
| Right side of the equation = | 9805 |
165 4 | X | = | 9805 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 9805 | ÷ | 165 4 |
| = | 9805 | × | 4 165 |
| = | 1961 | × | 4 33 |
We obtained :
| X | = | 7844 33 |
Convert the result to decimal form :
| X | = | 237.69697 |
