Workout 3 (-a + 2a - 4) = - 5

Let's solve your equation step-by-step. 3 (-a + 2a - 4) = - 5 Step 1: Simplify both sides of the equation. 3 (-a + 2a - 4) = - 5 (3) (-a) + (3) (2a) + (3) (-4) = - 5 (Distribute) - 3a + 6a + - 12 = - 5 ( - 3a + 6a) + (-12) = - 5 (Combine Like Terms) 3a + - 12 = - 5 3a - 12 = - 5 Step 2: Add 12 to both sides. 3a - 12 + 12 = - 5 + 12 3a = 7 Step 3: Divide both sides by 3. 3a / 3 = 7/3 a = 7/3 Answer: a = 7 / 3

3 (-a+2a-4) = - 5

3 (-a) + 3 (2a) - 3 (4) = - 5

-3a+6a-12=-5

+12 + 12

-3a+6a = 3a

3a=7
