Work: Find the solution of equation 0.13*x+(x*1.08+5)+0.15*x+(0.13*x*0.1655) = 143.8863 .
Question type: Equation
Solution:Original question:
13 100 | x | + | ( | x | × | 27 25 | + | 5 | ) | + | 3 20 | x | + | ( | 13 100 | x | × | 331 2000 | ) | = | 1438863 10000 |
| Left side of the equation = | 7 25 | x | + | ( | x | × | 27 25 | + | 5 | ) | + | ( | 13 100 | x | × | 331 2000 | ) |
7 25 | x | + | ( | x | × | 27 25 | + | 5 | ) | + | ( | 13 100 | x | × | 331 2000 | ) | = | 1438863 10000 |
| Left side of the equation = | 7 25 | x | + | x | × | 27 25 | + | 5 | + | ( | 13 100 | x | × | 331 2000 | ) |
| = | 34 25 | x | + | 5 | + | ( | 13 100 | x | × | 331 2000 | ) |
| = | 34 25 | x | + | 5 | + | 13 100 | x | × | 331 2000 |
| = | 34 25 | x | + | 5 | + | 4303 200000 | x |
| = | 276303 200000 | x | + | 5 |
276303 200000 | x | + | 5 | = | 1438863 10000 |
Transposition :
276303 200000 | x | = | 1438863 10000 | − | 5 |
Combine the items on the right of the equation:
276303 200000 | x | = | 1388863 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1388863 10000 | ÷ | 276303 200000 |
| = | 1388863 10000 | × | 200000 276303 |
| = | 1388863 | × | 20 276303 |
We obtained :
| x | = | 27777260 276303 |
Convert the result to decimal form :
| x | = | 100.53188 |
