Work: Find the solution of equation 2089.82+x = 0.15*(17174+x) .
Question type: Equation
Solution:Original question:
104491 50 | + | x | = | 3 20 | ( | 17174 | + | x | ) |
| Right side of the equation = | 3 20 | × | 17174 | + | 3 20 | x |
| = | 25761 10 | + | 3 20 | x |
104491 50 | + | x | = | 25761 10 | + | 3 20 | x |
Transposition :
| x | − | 3 20 | x | = | 25761 10 | − | 104491 50 |
Combine the items on the left of the equation:
17 20 | x | = | 25761 10 | − | 104491 50 |
Combine the items on the right of the equation:
17 20 | x | = | 12157 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 12157 25 | ÷ | 17 20 |
| = | 12157 25 | × | 20 17 |
| = | 12157 5 | × | 4 17 |
We obtained :
| x | = | 48628 85 |
Convert the result to decimal form :
| x | = | 572.094118 |
