☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation 5x-13 = 1.4×5 .
Question type: Equation
Solution:Original question:
| 5 | x | − | 13 | = | 7 5 | × | 5 |
| Right side of the equation = | 7 |
| 5 | x | − | 13 | = | 7 |
Transposition :
| 5 | x | = | 7 | + | 13 |
Combine the items on the right of the equation:
| 5 | x | = | 20 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 20 | ÷ | 5 |
| = | 20 | × | 1 5 |
| = | 4 | × | 1 |
We obtained :
| x | = | 4 |
