[ 1/1 Equation]
Work: Find the solution of equation 42x0.82+20x0.18 = 12250 .
Question type: Equation
Solution:Original question:
| 42 | x | × | 41 50 | + | 20 | x | × | 9 50 | = | 12250 |
| Left side of the equation = | 861 25 | x | + | 18 5 | x |
| = | 951 25 | x |
951 25 | x | = | 12250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 12250 | ÷ | 951 25 |
| = | 12250 | × | 25 951 |
We obtained :
| x | = | 306250 951 |
Convert the result to decimal form :
| x | = | 322.029443 |
