Work: Find the solution of equation 0.85*40x+0.15*15x = 16521*0.53 .
Question type: Equation
Solution:Original question:
17 20 | × | 40 | x | + | 3 20 | × | 15 | x | = | 16521 | × | 53 100 |
| Left side of the equation = | 34 | x | + | 9 4 | x |
| = | 145 4 | x |
145 4 | x | = | 16521 | × | 53 100 |
| Right side of the equation = | 875613 100 |
145 4 | x | = | 875613 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 875613 100 | ÷ | 145 4 |
| = | 875613 100 | × | 4 145 |
| = | 875613 25 | × | 1 145 |
We obtained :
| x | = | 875613 3625 |
Convert the result to decimal form :
| x | = | 241.548414 |
