[ 1/1 Equation]
Work: Find the solution of equation 450+x = (1500+x)*51% .
Question type: Equation
Solution:Original question:
| 450 | + | x | = | ( | 1500 | + | x | ) | × | 51 100 |
| Right side of the equation = | 1500 | × | 51 100 | + | x | × | 51 100 |
| = | 765 | + | x | × | 51 100 |
| 450 | + | x | = | 765 | + | 51 100 | x |
Transposition :
| x | − | 51 100 | x | = | 765 | − | 450 |
Combine the items on the left of the equation:
49 100 | x | = | 765 | − | 450 |
Combine the items on the right of the equation:
49 100 | x | = | 315 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 315 | ÷ | 49 100 |
| = | 315 | × | 100 49 |
| = | 45 | × | 100 7 |
We obtained :
| x | = | 4500 7 |
Convert the result to decimal form :
| x | = | 642.857143 |
