Answer:

First step is "Solve the parenthesis". It means subtract 1.5x from 4x.

Step-by-step explanation:

The given equation is

5(4x-1.5x)+12=4x-2

We need to find the first step o solve this equation.

Step 1: Solve the parenthesis.

5(2.5x)+12=4x-2

Step 2: Multiply.

12.5x+12=4x-2

Step 3: Isolate variable terms on left side.

12.5x-4x=-12-2

8.5x=-14

Step 4. Divide both sides by 8.5.

x=\dfrac{-14}{8.5}

x\approx -1.647

Therefore, the firs step is "Solve the parenthesis".
