Work: Find the solution of equation 2x－140 = 2628900 .
Question type: Equation
Solution:Original question:
| 2 | x | − | 140 | = | 2628900 |
Transposition :
| 2 | x | = | 2628900 | + | 140 |
Combine the items on the right of the equation:
| 2 | x | = | 2629040 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2629040 | ÷ | 2 |
| = | 2629040 | × | 1 2 |
| = | 1314520 | × | 1 |
We obtained :
| x | = | 1314520 |
