Work: Find the solution of equation 20*0.15X+44*0.85X = 18589*0.53 .
Question type: Equation
Solution:Original question:
| 20 | × | 3 20 | X | + | 44 | × | 17 20 | X | = | 18589 | × | 53 100 |
| Left side of the equation = | 3 | X | + | 187 5 | X |
| = | 202 5 | X |
202 5 | X | = | 18589 | × | 53 100 |
| Right side of the equation = | 985217 100 |
202 5 | X | = | 985217 100 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 985217 100 | ÷ | 202 5 |
| = | 985217 100 | × | 5 202 |
| = | 985217 20 | × | 1 202 |
We obtained :
| X | = | 985217 4040 |
Convert the result to decimal form :
| X | = | 243.865594 |
