Question

Solve the equation

v_{1} = - 16, v_{2} = 16

Evaluate

∣ 2 v ∣ - 4 = 28

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

∣ 2 v ∣ = 28 + 4

Add the numbers

∣ 2 v ∣ = 32

Separate the equation into 2 possible cases

2 v = 32 2 v = - 32

Solve the equation for v

More Steps

Evaluate

2 v = 32

Divide both sides

\frac{2 v}{2} = \frac{32}{2}

Divide the numbers

v = \frac{32}{2}

Divide the numbers

More Steps

Evaluate

\frac{32}{2}

Reduce the numbers

\frac{16}{1}

Calculate

16

v = 16

v = 16 2 v = - 32

Solve the equation for v

More Steps

Evaluate

2 v = - 32

Divide both sides

\frac{2 v}{2} = \frac{- 32}{2}

Divide the numbers

v = \frac{- 32}{2}

Divide the numbers

More Steps

Evaluate

\frac{- 32}{2}

Reduce the numbers

\frac{- 16}{1}

Calculate

- 16

v = - 16

v = 16 v = - 16

Solution

v_{1} = - 16, v_{2} = 16
