Step-by-step explanation:

Step 1: Define Equation

3.5(x + 12) = -2x + 18

Step 2: Solve for x

  1. Distribute 3.5:                    3.5x + 42 = -2x + 18
  2. Add 2x on both sides:       5.5x + 42 = 18
  3. Isolate x term:                    5.5x = -24
  4. Isolate x:                             x = -4.36364

Answer:

The answer I arrived at was x = -4.364

Step-by-step explanation:

3.5(x + 12) = -2x + 18

=> multiply 3.5 by everything in parenthesis

3.5x + 42 = -2x + 18

=> subtract 18 from both sides

3.5x + 24 = -2x

=> subtract 3.5x from both sides

24 = -5.5x

=> divide both sides by -5.5

-4.364 = x
