Work: Find the solution of equation 0.85*44X+0.15*20X = 15000*0.53 .
Question type: Equation
Solution:Original question:
17 20 | × | 44 | X | + | 3 20 | × | 20 | X | = | 15000 | × | 53 100 |
| Left side of the equation = | 187 5 | X | + | 3 | X |
| = | 202 5 | X |
202 5 | X | = | 15000 | × | 53 100 |
| Right side of the equation = | 7950 |
202 5 | X | = | 7950 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 7950 | ÷ | 202 5 |
| = | 7950 | × | 5 202 |
| = | 3975 | × | 5 101 |
We obtained :
| X | = | 19875 101 |
Convert the result to decimal form :
| X | = | 196.782178 |
