Work: Find the solution of equation 1.45*0.46*(1.48-x) = 0.52 .
Question type: Equation
Solution:Original question:
29 20 | × | 23 50 | ( | 37 25 | − | x | ) | = | 13 25 |
| Left side of the equation = | 667 1000 | ( | 37 25 | − | x | ) |
667 1000 | ( | 37 25 | − | x | ) | = | 13 25 |
| Left side of the equation = | 667 1000 | × | 37 25 | − | 667 1000 | x |
| = | 24679 25000 | − | 667 1000 | x |
24679 25000 | − | 667 1000 | x | = | 13 25 |
Transposition :
| - | 667 1000 | x | = | 13 25 | − | 24679 25000 |
Combine the items on the right of the equation:
| - | 667 1000 | x | = | - | 11679 25000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
11679 25000 | = | 667 1000 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
667 1000 | x | = | 11679 25000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 11679 25000 | ÷ | 667 1000 |
| = | 11679 25000 | × | 1000 667 |
| = | 11679 25 | × | 1 667 |
We obtained :
| x | = | 11679 16675 |
Convert the result to decimal form :
| x | = | 0.70039 |
