[ 2/2 Equation]
Work: Find the solution of equation 10 = 20t-5t .
Question type: Equation
Solution:Original question:
| 10 | = | 20 | t | − | 5 | t |
| Right side of the equation = | 15 | t |
| 10 | = | 15 | t |
Transposition :
| - | 15 | t | = | - | 10 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 10 | = | 15 | t |
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 :
| 15 | t | = | 10 |
The coefficient of the unknown number is reduced to 1 :
| t | = | 10 | ÷ | 15 |
| = | 10 | × | 1 15 |
| = | 2 | × | 1 3 |
We obtained :
| t | = | 2 3 |
Convert the result to decimal form :
| t | = | 0.666667 |
