Work: Find the solution of equation 0.85X*40+0.15X*15 = 11900*0.53 .
Question type: Equation
Solution:Original question:
17 20 | X | × | 40 | + | 3 20 | X | × | 15 | = | 11900 | × | 53 100 |
| Left side of the equation = | 34 | X | + | 9 4 | X |
| = | 145 4 | X |
145 4 | X | = | 11900 | × | 53 100 |
| Right side of the equation = | 6307 |
145 4 | X | = | 6307 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 6307 | ÷ | 145 4 |
| = | 6307 | × | 4 145 |
We obtained :
| X | = | 25228 145 |
Convert the result to decimal form :
| X | = | 173.986207 |
