[ 1/1 Equation]
Work: Find the solution of equation 5+(x*1.05+5)+0.15*x+(5*0.1655) = 411.44 .
Question type: Equation
Solution:Original question:
| 5 | + | ( | x | × | 21 20 | + | 5 | ) | + | 3 20 | x | + | ( | 5 | × | 331 2000 | ) | = | 10286 25 |
| Left side of the equation = | 5 | + | x | × | 21 20 | + | 5 | + | 3 20 | x | + | ( | 5 | × | 331 2000 | ) |
| = | 10 | + | 6 5 | x | + | ( | 5 | × | 331 2000 | ) |
| = | 10 | + | 6 5 | x | + | 5 | × | 331 2000 |
| = | 10 | + | 6 5 | x | + | 331 400 |
| = | 4331 400 | + | 6 5 | x |
4331 400 | + | 6 5 | x | = | 10286 25 |
Transposition :
6 5 | x | = | 10286 25 | − | 4331 400 |
Combine the items on the right of the equation:
6 5 | x | = | 32049 80 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 32049 80 | ÷ | 6 5 |
| = | 32049 80 | × | 5 6 |
| = | 10683 16 | × | 1 2 |
We obtained :
| x | = | 10683 32 |
Convert the result to decimal form :
| x | = | 333.84375 |
