Work: Find the solution of equation （y-1）+（y+5） = 0 .
Question type: Equation
Solution:Original question:
| ( | y | − | 1 | ) | + | ( | y | + | 5 | ) | = | 0 |
| Left side of the equation = | y | − | 1 | + | ( | y | + | 5 | ) |
| = | y | − | 1 | + | y | + | 5 |
| = | 2 | y | + | 4 |
| 2 | y | + | 4 | = | 0 |
Transposition :
| 2 | y | = | 0 | − | 4 |
Combine the items on the right of the equation:
| 2 | y | = | - | 4 |
The coefficient of the unknown number is reduced to 1 :
| y | = | - | 4 | ÷ | 2 |
| = | - | 4 | × | 1 2 |
| = | - | 2 | × | 1 |
We obtained :
| y | = | - | 2 |
