You are going to first have to write it as a rational equation.
Explanation:
2x - 1 =
2x(2x - 1) = x + 1
Now we can factor:
4x(x - 1) + 1(x - 1) = 0
(4x + 1)(x - 1) = 0
x =
Don't forget to state the restrictions on the variable, which in this case would be x
So, x =
Here are some practice exercises. Feel free to ask if you need help:
- What restrictions are on x?
a)
b)
- Solve each rational equation and state any restrictions on the variable.
a)
b)
Hopefully you understand now!
