[ 1/1 Equation]
Work: Find the solution of equation 0.15*15X+0.85*44X = 19631*0.53 .
Question type: Equation
Solution:Original question:
3 20 | × | 15 | X | + | 17 20 | × | 44 | X | = | 19631 | × | 53 100 |
| Left side of the equation = | 9 4 | X | + | 187 5 | X |
| = | 793 20 | X |
793 20 | X | = | 19631 | × | 53 100 |
| Right side of the equation = | 1040443 100 |
793 20 | X | = | 1040443 100 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 1040443 100 | ÷ | 793 20 |
| = | 1040443 100 | × | 20 793 |
| = | 1040443 5 | × | 1 793 |
We obtained :
| X | = | 1040443 3965 |
Convert the result to decimal form :
| X | = | 262.40681 |
