Solve 2x − 1 = 5.

x = 1
x = 2
x = 3
x = 4

1 answer

To solve the equation 2x - 1 = 5, we need to isolate the variable x.

Adding 1 to both sides of the equation, we get:
2x - 1 + 1 = 5 + 1
2x = 6

Dividing both sides of the equation by 2, we get:
2x/2 = 6/2
x = 3

Therefore, x = 3 is the solution to the equation 2x - 1 = 5.
