Answer 2

Sure, I'd be happy to help you solve the equation. Let's start by solving the equation step by step.

Step 1: Distribute the -2 on the left side of the equation

The original equation is: 0.2 - 2(x + 1) = 0.4x Distribute -2: 0.2 - 2x - 2 = 0.4x

Step 2: Combine like terms

Combine the constant terms on the left side: -1.8 - 2x = 0.4x

Step 3: Move the variable terms to one side

Add 2x to both sides of the equation to move the variable terms to the left side: -1.8 = 2x + 0.4x

Step 4: Combine like terms

Combine the x terms on the right side: -1.8 = 2.4x

Step 5: Solve for x

Now, we can solve for x by dividing both sides by 2.4: x = -1.8 / 2.4 x = -0.75

So, the solution to the equation 0.2 - 2(x + 1) = 0.4x is x = -0.75.
