[ 1/1 Equation]
Work: Find the solution of equation (18.6*17.15+24.98*x)/43.58 = 14.45 .
Question type: Equation
Solution:Original question:
| ( | 93 5 | × | 343 20 | + | 1249 50 | x | ) | ÷ | 2179 50 | = | 289 20 |
| Left side of the equation = | 93 5 | × | 343 20 | × | 50 2179 | + | 1249 50 | x | × | 50 2179 |
| = | 31899 4358 | + | 1249 2179 | x |
31899 4358 | + | 1249 2179 | x | = | 289 20 |
Transposition :
1249 2179 | x | = | 289 20 | − | 31899 4358 |
Combine the items on the right of the equation:
1249 2179 | x | = | 310741 43580 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 310741 43580 | ÷ | 1249 2179 |
| = | 310741 43580 | × | 2179 1249 |
We obtained :
| x | = | 677104639 54431420 |
By reducing fraction, we can get:
| x | = | 310741 24980 |
Convert the result to decimal form :
| x | = | 12.439592 |
