[ 1/1 Equation]
Work: Find the solution of equation 19.8×0.96×a+3 = 12.36 .
Question type: Equation
Solution:Original question:
99 5 | × | 24 25 | a | + | 3 | = | 309 25 |
| Left side of the equation = | 2376 125 | a | + | 3 |
2376 125 | a | + | 3 | = | 309 25 |
Transposition :
2376 125 | a | = | 309 25 | − | 3 |
Combine the items on the right of the equation:
2376 125 | a | = | 234 25 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 234 25 | ÷ | 2376 125 |
| = | 234 25 | × | 125 2376 |
| = | 13 | × | 5 132 |
We obtained :
| a | = | 65 132 |
Convert the result to decimal form :
| a | = | 0.492424 |
