Work: Find the solution of equation 36×a×0.76+3 = 21.9 .
Question type: Equation
Solution:Original question:
| 36 | a | × | 19 25 | + | 3 | = | 219 10 |
| Left side of the equation = | 684 25 | a | + | 3 |
684 25 | a | + | 3 | = | 219 10 |
Transposition :
684 25 | a | = | 219 10 | − | 3 |
Combine the items on the right of the equation:
684 25 | a | = | 189 10 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 189 10 | ÷ | 684 25 |
| = | 189 10 | × | 25 684 |
| = | 21 2 | × | 5 76 |
We obtained :
| a | = | 105 152 |
Convert the result to decimal form :
| a | = | 0.690789 |
