Work: Find the solution of equation 40 = a*3.7906+3.1045 .
Question type: Equation
Solution:Original question:
| 40 | = | a | × | 18953 5000 | + | 6209 2000 |
Transposition :
| - | 18953 5000 | a | = | 6209 2000 | − | 40 |
Combine the items on the right of the equation:
| - | 18953 5000 | a | = | - | 73791 2000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
73791 2000 | = | 18953 5000 | 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 :
18953 5000 | a | = | 73791 2000 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 73791 2000 | ÷ | 18953 5000 |
| = | 73791 2000 | × | 5000 18953 |
| = | 73791 2 | × | 5 18953 |
We obtained :
| a | = | 368955 37906 |
Convert the result to decimal form :
| a | = | 9.73342 |
