Work: Find the solution of equation 16000+32100+4000+2296.51+254+590.84+325.36+699.1+5301.68+3837.14+4050.6+1687.51 = a*0.7 .
Question type: Equation
Solution:Original question:
| 16000 | + | 32100 | + | 4000 | + | 229651 100 | + | 254 | + | 14771 25 | + | 8134 25 | + | 6991 10 | + | 132542 25 | + | 191857 50 | + | 20253 5 | + | 168751 100 | = | a | × | 7 10 |
| Left side of the equation = | 3557137 50 |
3557137 50 | = | a | × | 7 10 |
Transposition :
| - | 7 10 | a | = | - | 3557137 50 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
3557137 50 | = | 7 10 | a |
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 :
7 10 | a | = | 3557137 50 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 3557137 50 | ÷ | 7 10 |
| = | 3557137 50 | × | 10 7 |
| = | 3557137 5 | × | 1 7 |
We obtained :
| a | = | 3557137 35 |
Convert the result to decimal form :
| a | = | 101632.485714 |
