Work: Find the solution of equation 43*0.9x+15*0.1X = 9832*0.59 .
Question type: Equation
Solution:Original question:
| 43 | × | 9 10 | x | + | 15 | × | 1 10 | x | = | 9832 | × | 59 100 |
| Left side of the equation = | 387 10 | x | + | 3 2 | x |
| = | 201 5 | x |
201 5 | x | = | 9832 | × | 59 100 |
| Right side of the equation = | 145022 25 |
201 5 | x | = | 145022 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 145022 25 | ÷ | 201 5 |
| = | 145022 25 | × | 5 201 |
| = | 145022 5 | × | 1 201 |
We obtained :
| x | = | 145022 1005 |
Convert the result to decimal form :
| x | = | 144.300498 |
