[ 1/1 Equation]
Work: Find the solution of equation 40*0.9x+15*0.1X = 14838*0.38 .
Question type: Equation
Solution:Original question:
| 40 | × | 9 10 | x | + | 15 | × | 1 10 | x | = | 14838 | × | 19 50 |
| Left side of the equation = | 36 | x | + | 3 2 | x |
| = | 75 2 | x |
75 2 | x | = | 14838 | × | 19 50 |
| Right side of the equation = | 140961 25 |
75 2 | x | = | 140961 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 140961 25 | ÷ | 75 2 |
| = | 140961 25 | × | 2 75 |
| = | 46987 25 | × | 2 25 |
We obtained :
| x | = | 93974 625 |
Convert the result to decimal form :
| x | = | 150.3584 |
