[ 1/1 Equation]
Work: Find the solution of equation (5-x)/19+(3.3-x)20.33 = x/0.015 .
Question type: Equation
Solution:Original question:
| ( | 5 | − | x | ) | ÷ | 19 | + | ( | 33 10 | − | x | ) | × | 2033 100 | = | x | ÷ | 3 200 |
| Left side of the equation = | 5 | × | 1 19 | − | x | × | 1 19 | + | ( | 33 10 | − | x | ) | × | 2033 100 |
| = | 5 19 | − | x | × | 1 19 | + | ( | 33 10 | − | x | ) | × | 2033 100 |
| = | 5 19 | − | 1 19 | x | + | 33 10 | × | 2033 100 | − | x | × | 2033 100 |
| = | 5 19 | − | 1 19 | x | + | 67089 1000 | − | x | × | 2033 100 |
| = | 1279691 19000 | − | 38727 1900 | x |
1279691 19000 | − | 38727 1900 | x | = | x | ÷ | 3 200 |
Transposition :
| - | 38727 1900 | x | − | 200 3 | x | = | - | 1279691 19000 |
Combine the items on the left of the equation:
| - | 496181 5700 | x | = | - | 1279691 19000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1279691 19000 | = | 496181 5700 | 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 :
496181 5700 | x | = | 1279691 19000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1279691 19000 | ÷ | 496181 5700 |
| = | 1279691 19000 | × | 5700 496181 |
| = | 182813 10 | × | 3 70883 |
We obtained :
| x | = | 548439 708830 |
Convert the result to decimal form :
| x | = | 0.773724 |
