[ 1/1 Equation]
Work: Find the solution of equation 20.7×a×0.65+3 = 12.38 .
Question type: Equation
Solution:Original question:
207 10 | a | × | 13 20 | + | 3 | = | 619 50 |
| Left side of the equation = | 2691 200 | a | + | 3 |
2691 200 | a | + | 3 | = | 619 50 |
Transposition :
2691 200 | a | = | 619 50 | − | 3 |
Combine the items on the right of the equation:
2691 200 | a | = | 469 50 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 469 50 | ÷ | 2691 200 |
| = | 469 50 | × | 200 2691 |
| = | 469 | × | 4 2691 |
We obtained :
| a | = | 1876 2691 |
Convert the result to decimal form :
| a | = | 0.697139 |
