Step-by-step explanation:

Step 1: Define equation

-12(a - 2) = -50

Step 2: Solve for a

  1. Divide -12 on both sides:                    a - 2 = 25/6
  2. Add 2 on both sides:                          a = 37/6

Step 3: Check

Plug in a into the original equation to verify it's a solution.

  1. Substitute in a:                    -12(37/6 - 2) = -50
  2. Subtract:                              -12(25/6) = -50
  3. Multiply:                               -50 = -50

Here we see that -50 does indeed equal -50.

∴ a = 37/6 is a solution of the equation.

Answer:

a = [tex]\frac{37}{6}[/tex]

Step-by-step explanation:

-12(a - 2) = -50

-12a + 24 = -50

-12a = -74

a = [tex]\frac{74}{12}[/tex] = [tex]\frac{37}{6}[/tex]
