Work: Find the solution of equation 5*x+32*4.79 = 4.89*x+32*4.89 .
Question type: Equation
Solution:Original question:
| 5 | x | + | 32 | × | 479 100 | = | 489 100 | x | + | 32 | × | 489 100 |
| Left side of the equation = | 5 | x | + | 3832 25 |
| 5 | x | + | 3832 25 | = | 489 100 | x | + | 32 | × | 489 100 |
| Right side of the equation = | 489 100 | x | + | 3912 25 |
| 5 | x | + | 3832 25 | = | 489 100 | x | + | 3912 25 |
Transposition :
| 5 | x | − | 489 100 | x | = | 3912 25 | − | 3832 25 |
Combine the items on the left of the equation:
11 100 | x | = | 3912 25 | − | 3832 25 |
Combine the items on the right of the equation:
11 100 | x | = | 16 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 16 5 | ÷ | 11 100 |
| = | 16 5 | × | 100 11 |
| = | 16 | × | 20 11 |
We obtained :
| x | = | 320 11 |
Convert the result to decimal form :
| x | = | 29.090909 |
