Work: Find the solution of equation 4*x+17.67*(1-x) = 10 .
Question type: Equation
Solution:Original question:
| 4 | x | + | 1767 100 | ( | 1 | − | x | ) | = | 10 |
| Left side of the equation = | 4 | x | + | 1767 100 | × | 1 | − | 1767 100 | x |
| = | 4 | x | + | 1767 100 | − | 1767 100 | x |
| = | - | 1367 100 | x | + | 1767 100 |
| - | 1367 100 | x | + | 1767 100 | = | 10 |
Transposition :
| - | 1367 100 | x | = | 10 | − | 1767 100 |
Combine the items on the right of the equation:
| - | 1367 100 | x | = | - | 767 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
767 100 | = | 1367 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 :
1367 100 | x | = | 767 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 767 100 | ÷ | 1367 100 |
| = | 767 100 | × | 100 1367 |
| = | 767 | × | 1 1367 |
We obtained :
| x | = | 767 1367 |
Convert the result to decimal form :
| x | = | 0.561083 |
