[ 1/1 Equation]
Work: Find the solution of equation 11+x = (20+x)*0.6667 .
Question type: Equation
Solution:Original question:
| 11 | + | x | = | ( | 20 | + | x | ) | × | 6667 10000 |
| Right side of the equation = | 20 | × | 6667 10000 | + | x | × | 6667 10000 |
| = | 6667 500 | + | x | × | 6667 10000 |
| 11 | + | x | = | 6667 500 | + | 6667 10000 | x |
Transposition :
| x | − | 6667 10000 | x | = | 6667 500 | − | 11 |
Combine the items on the left of the equation:
3333 10000 | x | = | 6667 500 | − | 11 |
Combine the items on the right of the equation:
3333 10000 | x | = | 1167 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1167 500 | ÷ | 3333 10000 |
| = | 1167 500 | × | 10000 3333 |
| = | 389 | × | 20 1111 |
We obtained :
| x | = | 7780 1111 |
Convert the result to decimal form :
| x | = | 7.0027 |
