☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation x-（x*0.1%） = 272.19-0.05 .
Question type: Equation
Solution:Original question:
| x | − | ( | x | × | 1 1000 | ) | = | 27219 100 | − | 1 20 |
| Left side of the equation = | x | − | x | × | 1 1000 |
| = | 999 1000 | x |
999 1000 | x | = | 27219 100 | − | 1 20 |
| Right side of the equation = | 13607 50 |
999 1000 | x | = | 13607 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 13607 50 | ÷ | 999 1000 |
| = | 13607 50 | × | 1000 999 |
| = | 13607 | × | 20 999 |
We obtained :
| x | = | 272140 999 |
Convert the result to decimal form :
| x | = | 272.412412 |
