[ 1/1 Equation]
Work: Find the solution of equation 0.5x+5 = 0.6x-75 .
Question type: Equation
Solution:Original question:
1 2 | x | + | 5 | = | 3 5 | x | − | 75 |
Transposition :
1 2 | x | − | 3 5 | x | = | - | 75 | − | 5 |
Combine the items on the left of the equation:
| - | 1 10 | x | = | - | 75 | − | 5 |
Combine the items on the right of the equation:
| - | 1 10 | x | = | - | 80 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 80 | = | 1 10 | x |
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 :
1 10 | x | = | 80 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 80 | ÷ | 1 10 |
| = | 80 | × | 10 |
We obtained :
| x | = | 800 |
