Answer:
First step is "Solve the parenthesis". It means subtract 1.5x from 4x.
Step-by-step explanation:
The given equation is
[tex]5(4x-1.5x)+12=4x-2[/tex]
We need to find the first step o solve this equation.
Step 1: Solve the parenthesis.
[tex]5(2.5x)+12=4x-2[/tex]
Step 2: Multiply.
[tex]12.5x+12=4x-2[/tex]
Step 3: Isolate variable terms on left side.
[tex]12.5x-4x=-12-2[/tex]
[tex]8.5x=-14[/tex]
Step 4. Divide both sides by 8.5.
[tex]x=\dfrac{-14}{8.5}[/tex]
[tex]x\approx -1.647[/tex]
Therefore, the firs step is "Solve the parenthesis".
