Work: Find the solution of equation 11.8×a×0.76+3 = 9.9 .
Question type: Equation
Solution:Original question:
59 5 | a | × | 19 25 | + | 3 | = | 99 10 |
| Left side of the equation = | 1121 125 | a | + | 3 |
1121 125 | a | + | 3 | = | 99 10 |
Transposition :
1121 125 | a | = | 99 10 | − | 3 |
Combine the items on the right of the equation:
1121 125 | a | = | 69 10 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 69 10 | ÷ | 1121 125 |
| = | 69 10 | × | 125 1121 |
| = | 69 2 | × | 25 1121 |
We obtained :
| a | = | 1725 2242 |
Convert the result to decimal form :
| a | = | 0.769402 |
