Work: Find the solution of equation 0.85*43x+0.15*15x = 12576*0.53 .
Question type: Equation
Solution:Original question:
17 20 | × | 43 | x | + | 3 20 | × | 15 | x | = | 12576 | × | 53 100 |
| Left side of the equation = | 731 20 | x | + | 9 4 | x |
| = | 194 5 | x |
194 5 | x | = | 12576 | × | 53 100 |
| Right side of the equation = | 166632 25 |
194 5 | x | = | 166632 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 166632 25 | ÷ | 194 5 |
| = | 166632 25 | × | 5 194 |
| = | 83316 5 | × | 1 97 |
We obtained :
| x | = | 83316 485 |
Convert the result to decimal form :
| x | = | 171.785567 |
