☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation X-10 = 4(X-22) .
Question type: Equation
Solution:Original question:
| X | − | 10 | = | 4 | ( | X | − | 22 | ) |
| Right side of the equation = | 4 | X | − | 4 | × | 22 |
| = | 4 | X | − | 88 |
| X | − | 10 | = | 4 | X | − | 88 |
Transposition :
| X | − | 4 | X | = | - | 88 | + | 10 |
Combine the items on the left of the equation:
| - | 3 | X | = | - | 88 | + | 10 |
Combine the items on the right of the equation:
| - | 3 | X | = | - | 78 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 78 | = | 3 | 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 :
| 3 | X | = | 78 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 78 | ÷ | 3 |
| = | 78 | × | 1 3 |
| = | 26 | × | 1 |
We obtained :
| X | = | 26 |
