[ 1/1 Equation]
Work: Find the solution of equation 1000000 = 500Q-（6000000+250Q） .
Question type: Equation
Solution:Original question:
| 1000000 | = | 500 | Q | − | ( | 6000000 | + | 250 | Q | ) |
| Right side of the equation = | 500 | Q | − | 6000000 | − | 250 | Q |
| = | 250 | Q | − | 6000000 |
| 1000000 | = | 250 | Q | − | 6000000 |
Transposition :
| - | 250 | Q | = | - | 6000000 | − | 1000000 |
Combine the items on the right of the equation:
| - | 250 | Q | = | - | 7000000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 7000000 | = | 250 | Q |
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 :
| 250 | Q | = | 7000000 |
The coefficient of the unknown number is reduced to 1 :
| Q | = | 7000000 | ÷ | 250 |
| = | 7000000 | × | 1 250 |
| = | 28000 | × | 1 |
We obtained :
| Q | = | 28000 |
