Work: Find the solution of equation 40*0.85x+15*0.15x = 14310 .
Question type: Equation
Solution:Original question:
| 40 | × | 17 20 | x | + | 15 | × | 3 20 | x | = | 14310 |
| Left side of the equation = | 34 | x | + | 9 4 | x |
| = | 145 4 | x |
145 4 | x | = | 14310 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 14310 | ÷ | 145 4 |
| = | 14310 | × | 4 145 |
| = | 2862 | × | 4 29 |
We obtained :
| x | = | 11448 29 |
Convert the result to decimal form :
| x | = | 394.758621 |
