[ 1/1 Equation]
Work: Find the solution of equation 15+(x*1.08+2.5)+0.15*x+(15*0.1655) = 114.2 .
Question type: Equation
Solution:Original question:
| 15 | + | ( | x | × | 27 25 | + | 5 2 | ) | + | 3 20 | x | + | ( | 15 | × | 331 2000 | ) | = | 571 5 |
| Left side of the equation = | 15 | + | x | × | 27 25 | + | 5 2 | + | 3 20 | x | + | ( | 15 | × | 331 2000 | ) |
| = | 35 2 | + | 123 100 | x | + | ( | 15 | × | 331 2000 | ) |
| = | 35 2 | + | 123 100 | x | + | 15 | × | 331 2000 |
| = | 35 2 | + | 123 100 | x | + | 993 400 |
| = | 7993 400 | + | 123 100 | x |
7993 400 | + | 123 100 | x | = | 571 5 |
Transposition :
123 100 | x | = | 571 5 | − | 7993 400 |
Combine the items on the right of the equation:
123 100 | x | = | 37687 400 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 37687 400 | ÷ | 123 100 |
| = | 37687 400 | × | 100 123 |
| = | 37687 4 | × | 1 123 |
We obtained :
| x | = | 37687 492 |
Convert the result to decimal form :
| x | = | 76.599593 |
