Work: Find the solution of equation (530-x)/10.5 = 35-x/19.3 .
Question type: Equation
Solution:Original question:
| ( | 530 | − | x | ) | ÷ | 21 2 | = | 35 | − | x | ÷ | 193 10 |
| Left side of the equation = | 530 | × | 2 21 | − | x | × | 2 21 |
| = | 1060 21 | − | x | × | 2 21 |
1060 21 | − | 2 21 | x | = | 35 | − | x | ÷ | 193 10 |
Transposition :
| - | 2 21 | x | + | 10 193 | x | = | 35 | − | 1060 21 |
Combine the items on the left of the equation:
| - | 176 4053 | x | = | 35 | − | 1060 21 |
Combine the items on the right of the equation:
| - | 176 4053 | x | = | - | 325 21 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
325 21 | = | 176 4053 | 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 :
176 4053 | x | = | 325 21 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 325 21 | ÷ | 176 4053 |
| = | 325 21 | × | 4053 176 |
| = | 325 | × | 193 176 |
We obtained :
| x | = | 62725 176 |
Convert the result to decimal form :
| x | = | 356.392045 |
