-12 = -5(x - 3) ......​
Gnoma [55]

Answer:

x = 27/5

Step-by-step explanation:

Step 1: Write equation

-12 = -5(x - 3)

Step 2: Solve for <em>x</em>

  1. Distribute -5: -12 = -5x + 15
  2. Subtract 15 on both sides: -27 = -5x
  3. Divide both sides by -5: x = 27/5

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

-12 = -5(27/5 - 3)

-12 = -5(12/5)

-12 = -12
