Type your math problem... |3x|=9

x

Question

Solve the equation

x_{1} = - 3, x_{2} = 3

Evaluate

∣ 3 x ∣ = 9

Separate the equation into 2 possible cases

3 x = 9 3 x = - 9

Solve the equation for x

More Steps

Evaluate

3 x = 9

Divide both sides

\frac{3 x}{3} = \frac{9}{3}

Divide the numbers

x = \frac{9}{3}

Divide the numbers

More Steps

Evaluate

\frac{9}{3}

Reduce the numbers

\frac{3}{1}

Calculate

3

x = 3

x = 3 3 x = - 9

Solve the equation for x

More Steps

Evaluate

3 x = - 9

Divide both sides

\frac{3 x}{3} = \frac{- 9}{3}

Divide the numbers

x = \frac{- 9}{3}

Divide the numbers

More Steps

Evaluate

\frac{- 9}{3}

Reduce the numbers

\frac{- 3}{1}

Calculate

- 3

x = - 3

x = 3 x = - 3
