Work: Find the solution of equation 263+x = 0.87*(345+x) .
Question type: Equation
Solution:Original question:
| 263 | + | x | = | 87 100 | ( | 345 | + | x | ) |
| Right side of the equation = | 87 100 | × | 345 | + | 87 100 | x |
| = | 6003 20 | + | 87 100 | x |
| 263 | + | x | = | 6003 20 | + | 87 100 | x |
Transposition :
| x | − | 87 100 | x | = | 6003 20 | − | 263 |
Combine the items on the left of the equation:
13 100 | x | = | 6003 20 | − | 263 |
Combine the items on the right of the equation:
13 100 | x | = | 743 20 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 743 20 | ÷ | 13 100 |
| = | 743 20 | × | 100 13 |
| = | 743 | × | 5 13 |
We obtained :
| x | = | 3715 13 |
Convert the result to decimal form :
| x | = | 285.769231 |
