Work: Find the solution of equation 570 = 0.3b+b .
Question type: Equation
Solution:Original question:
| 570 | = | 3 10 | b | + | b |
| Right side of the equation = | 13 10 | b |
| 570 | = | 13 10 | b |
Transposition :
| - | 13 10 | b | = | - | 570 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 570 | = | 13 10 | b |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
13 10 | b | = | 570 |
The coefficient of the unknown number is reduced to 1 :
| b | = | 570 | ÷ | 13 10 |
| = | 570 | × | 10 13 |
We obtained :
| b | = | 5700 13 |
Convert the result to decimal form :
| b | = | 438.461538 |
