x

Question

Find the roots

x = \frac{1}{2}

Alternative Form

x = 0.5

Evaluate

2 x - 1

To find the roots of the expression,set the expression equal to 0

2 x - 1 = 0

Move the constant to the right-hand side and change its sign

2 x = 0 + 1

Removing 0 doesn't change the value,so remove it from the expression

2 x = 1

Divide both sides

\frac{2 x}{2} = \frac{1}{2}

Solution

x = \frac{1}{2}

Alternative Form

x = 0.5
