Work: Find the solution of equation 2.51(6-x) = 10 .
Question type: Equation
Solution:Original question:
251 100 | ( | 6 | − | x | ) | = | 10 |
| Left side of the equation = | 251 100 | × | 6 | − | 251 100 | x |
| = | 753 50 | − | 251 100 | x |
753 50 | − | 251 100 | x | = | 10 |
Transposition :
| - | 251 100 | x | = | 10 | − | 753 50 |
Combine the items on the right of the equation:
| - | 251 100 | x | = | - | 253 50 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
253 50 | = | 251 100 | 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 :
251 100 | x | = | 253 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 253 50 | ÷ | 251 100 |
| = | 253 50 | × | 100 251 |
| = | 253 | × | 2 251 |
We obtained :
| x | = | 506 251 |
Convert the result to decimal form :
| x | = | 2.015936 |
