Work: Find the solution of equation 0.85*44X+0.15*15X = 27500*0.5 .
Question type: Equation
Solution:Original question:
17 20 | × | 44 | X | + | 3 20 | × | 15 | X | = | 27500 | × | 1 2 |
| Left side of the equation = | 187 5 | X | + | 9 4 | X |
| = | 793 20 | X |
793 20 | X | = | 27500 | × | 1 2 |
| Right side of the equation = | 13750 |
793 20 | X | = | 13750 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 13750 | ÷ | 793 20 |
| = | 13750 | × | 20 793 |
We obtained :
| X | = | 275000 793 |
Convert the result to decimal form :
| X | = | 346.784363 |
