Work: Find the solution of equation 2.68*2.191 = 1.46*(x+2.191) .
Question type: Equation
Solution:Original question:
67 25 | × | 2191 1000 | = | 73 50 | ( | x | + | 2191 1000 | ) |
| Left side of the equation = | 146797 25000 |
146797 25000 | = | 73 50 | ( | x | + | 2191 1000 | ) |
| Right side of the equation = | 73 50 | x | + | 73 50 | × | 2191 1000 |
| = | 73 50 | x | + | 159943 50000 |
146797 25000 | = | 73 50 | x | + | 159943 50000 |
Transposition :
| - | 73 50 | x | = | 159943 50000 | − | 146797 25000 |
Combine the items on the right of the equation:
| - | 73 50 | x | = | - | 133651 50000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
133651 50000 | = | 73 50 | 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 :
73 50 | x | = | 133651 50000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 133651 50000 | ÷ | 73 50 |
| = | 133651 50000 | × | 50 73 |
| = | 133651 1000 | × | 1 73 |
We obtained :
| x | = | 133651 73000 |
Convert the result to decimal form :
| x | = | 1.830836 |
