Solve -5|-8r| = -10

Evaluate

- 5 ∣ - 8 r ∣ = - 10

Calculate the absolute value

- 5 ∣ 8 r ∣ = - 10

Change the sign

5 ∣ 8 r ∣ = 10

Divide both sides

\frac{5 ∣ 8 r ∣}{5} = \frac{10}{5}

Divide the numbers

∣ 8 r ∣ = \frac{10}{5}

Divide the numbers

More Steps

∣ 8 r ∣ = 2

Separate the equation into 2 possible cases

8 r = 2 8 r = - 2

Solve the equation for r

More Steps

r = \frac{1}{4} 8 r = - 2
