x = 3
explain
To solve the equation 2x - 1 = 5, we can isolate the variable x by performing the necessary operations to get x on one side of the equation.
Starting with the given equation:
2x - 1 = 5
First, we can add 1 to both sides of the equation to get rid of the -1 on the left side:
2x - 1 + 1 = 5 + 1
2x = 6
Next, we divide both sides of the equation by 2 to solve for x:
2x/2 = 6/2
x = 3
Therefore, the solution to the equation 2x - 1 = 5 is x = 3.
