Type your math problem... |2x| = 4

x

Question

Solve the equation

x_{1} = - 2, x_{2} = 2

Evaluate

∣ 2 x ∣ = 4

Separate the equation into 2 possible cases

2 x = 4 2 x = - 4

Solve the equation for x

More Steps

Evaluate

2 x = 4

Divide both sides

\frac{2 x}{2} = \frac{4}{2}

Divide the numbers

x = \frac{4}{2}

Divide the numbers

More Steps

Evaluate

\frac{4}{2}

Reduce the numbers

\frac{2}{1}

Calculate

2

x = 2

x = 2 2 x = - 4

Solve the equation for x

More Steps

Evaluate

2 x = - 4

Divide both sides

\frac{2 x}{2} = \frac{- 4}{2}

Divide the numbers

x = \frac{- 4}{2}

Divide the numbers

More Steps

Evaluate

\frac{- 4}{2}

Reduce the numbers

\frac{- 2}{1}

Calculate

- 2

x = - 2

x = 2 x = - 2

Solution

x_{1} = - 2, x_{2} = 2
