( | 2 | + | 10 | x | ) | ÷ | ( | x | + | 1 | ) | = | 193 20 |
Multiply both sides of the equation by: | ( | x | + | 1 | ) |
( | 2 | + | 10 | x | ) | = | 193 20 | ( | x | + | 1 | ) |
2 | + | 10 | x | = | 193 20 | ( | x | + | 1 | ) |
2 | + | 10 | x | = | 193 20 | x | + | 193 20 | × | 1 |
2 | + | 10 | x | = | 193 20 | x | + | 193 20 |
10 | x | − | 193 20 | x | = | 193 20 | − | 2 |
7 20 | x | = | 193 20 | − | 2 |
7 20 | x | = | 153 20 |
x | = | 153 20 | ÷ | 7 20 |
= | 153 20 | × | 20 7 |
= | 153 | × | 1 7 |
x | = | 153 7 |
x | = | 21.857143 |
