[ 1/1 Equation]
Work: Find the solution of equation 4/3*（1-2y） = 0 .
Question type: Equation
Solution:Original question:
| 4 | ÷ | 3 | × | ( | 1 | − | 2 | y | ) | = | 0 |
| Left side of the equation = | 4 3 | ( | 1 | − | 2 | y | ) |
4 3 | ( | 1 | − | 2 | y | ) | = | 0 |
| Left side of the equation = | 4 3 | × | 1 | − | 4 3 | × | 2 | y |
| = | 4 3 | − | 8 3 | y |
4 3 | − | 8 3 | y | = | 0 |
Transposition :
| - | 8 3 | y | = | 0 | − | 4 3 |
Combine the items on the right of the equation:
| - | 8 3 | y | = | - | 4 3 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
4 3 | = | 8 3 | y |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
8 3 | y | = | 4 3 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 4 3 | ÷ | 8 3 |
| = | 4 3 | × | 3 8 |
| = | 1 | × | 1 2 |
We obtained :
| y | = | 1 2 |
Convert the result to decimal form :
| y | = | 0.5 |
