Work: Find the solution of equation (R/R+1)*0.4821+(0.98/R+1) = 0.7011 .
Question type: Equation
Solution:Original question:
| ( | R | ÷ | R | + | 1 | ) | × | 4821 10000 | + | ( | 49 50 | ÷ | R | + | 1 | ) | = | 7011 10000 |
| R | ÷ | R | × | 4821 10000 | + | 1 | × | 4821 10000 | + | ( | 49 50 | ÷ | R | + | 1 | ) | = | 7011 10000 |
| R | ÷ | R | × | 4821 10000 | + | 4821 10000 | + | ( | 49 50 | ÷ | R | + | 1 | ) | = | 7011 10000 |
| 1 | ÷ | 1 | × | 4821 10000 | + | 4821 10000 | + | 49 50 | ÷ | R | + | 1 | = | 7011 10000 |
4821 10000 | + | 4821 10000 | + | 49 50 | ÷ | R | + | 1 | = | 7011 10000 |
9821 5000 | + | 49 50 | ÷ | R | = | 7011 10000 |
| Multiply both sides of the equation by: | R |
9821 5000 | R | + | 49 50 | = | 7011 10000 | R |
Transposition :
9821 5000 | R | − | 7011 10000 | R | = | - | 49 50 |
Combine the items on the left of the equation:
12631 10000 | R | = | - | 49 50 |
The coefficient of the unknown number is reduced to 1 :
| R | = | - | 49 50 | ÷ | 12631 10000 |
| = | - | 49 50 | × | 10000 12631 |
| = | - | 49 | × | 200 12631 |
We obtained :
| R | = | - | 9800 12631 |
Convert the result to decimal form :
| R | = | - 0.775869 |
