[ 1/1 Equation]
Work: Find the solution of equation x+1/15+(x+3/12) = 1 .
Question type: Equation
Solution:Original question:
| x | + | 1 | ÷ | 15 | + | ( | x | + | 3 | ÷ | 12 | ) | = | 1 |
| Left side of the equation = | x | + | 1 15 | + | ( | x | + | 3 | ÷ | 12 | ) |
| x | + | 1 15 | + | ( | x | + | 3 | ÷ | 12 | ) | = | 1 |
| Left side of the equation = | x | + | 1 15 | + | x | + | 3 | ÷ | 12 |
| = | x | + | 1 15 | + | x | + | 1 4 |
| = | 2 | x | + | 19 60 |
| 2 | x | + | 19 60 | = | 1 |
Transposition :
| 2 | x | = | 1 | − | 19 60 |
Combine the items on the right of the equation:
| 2 | x | = | 41 60 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 41 60 | ÷ | 2 |
| = | 41 60 | × | 1 2 |
We obtained :
| x | = | 41 120 |
Convert the result to decimal form :
| x | = | 0.341667 |
