[ 2/3 Equation]
Work: Find the solution of equation 一x+2 = 42×5 .
Question type: Equation
Solution:Original question:
| - | x | + | 2 | = | 42 | × | 5 |
| Right side of the equation = | 210 |
| - | x | + | 2 | = | 210 |
Transposition :
| - | x | = | 210 | − | 2 |
Combine the items on the right of the equation:
| - | x | = | 208 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 208 | = | 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 :
| x | = | - | 208 |
This is the solution of the equation.
