Work: Find the solution of equation 0.85*42X+0.15*15X = 18380*0.53 .
Question type: Equation
Solution:Original question:
17 20 | × | 42 | X | + | 3 20 | × | 15 | X | = | 18380 | × | 53 100 |
| Left side of the equation = | 357 10 | X | + | 9 4 | X |
| = | 759 20 | X |
759 20 | X | = | 18380 | × | 53 100 |
| Right side of the equation = | 48707 5 |
759 20 | X | = | 48707 5 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 48707 5 | ÷ | 759 20 |
| = | 48707 5 | × | 20 759 |
| = | 48707 | × | 4 759 |
We obtained :
| X | = | 194828 759 |
Convert the result to decimal form :
| X | = | 256.690382 |
