[ 1/1 Equation]
Work: Find the solution of equation x/0.229 = (18-x)/0.029 .
Question type: Equation
Solution:Original question:
| x | ÷ | 229 1000 | = | ( | 18 | − | x | ) | ÷ | 29 1000 |
| Right side of the equation = | 18 | × | 1000 29 | − | x | × | 1000 29 |
| = | 18000 29 | − | x | × | 1000 29 |
1000 229 | x | = | 18000 29 | − | 1000 29 | x |
Transposition :
1000 229 | x | + | 1000 29 | x | = | 18000 29 |
Combine the items on the left of the equation:
258000 6641 | x | = | 18000 29 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 18000 29 | ÷ | 258000 6641 |
| = | 18000 29 | × | 6641 258000 |
| = | 3 | × | 229 43 |
We obtained :
| x | = | 687 43 |
Convert the result to decimal form :
| x | = | 15.976744 |
