[ 1/1 Equation]
Work: Find the solution of equation 10+(x*1.02+2.5)+0.15*x+(10*0.1655) = 48 .
Question type: Equation
Solution:Original question:
| 10 | + | ( | x | × | 51 50 | + | 5 2 | ) | + | 3 20 | x | + | ( | 10 | × | 331 2000 | ) | = | 48 |
| Left side of the equation = | 10 | + | x | × | 51 50 | + | 5 2 | + | 3 20 | x | + | ( | 10 | × | 331 2000 | ) |
| = | 25 2 | + | 117 100 | x | + | ( | 10 | × | 331 2000 | ) |
| = | 25 2 | + | 117 100 | x | + | 10 | × | 331 2000 |
| = | 25 2 | + | 117 100 | x | + | 331 200 |
| = | 2831 200 | + | 117 100 | x |
2831 200 | + | 117 100 | x | = | 48 |
Transposition :
117 100 | x | = | 48 | − | 2831 200 |
Combine the items on the right of the equation:
117 100 | x | = | 6769 200 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 6769 200 | ÷ | 117 100 |
| = | 6769 200 | × | 100 117 |
| = | 6769 2 | × | 1 117 |
We obtained :
| x | = | 6769 234 |
Convert the result to decimal form :
| x | = | 28.92735 |
