Answer 3

It seems like you've provided an equation, but there might be a mistake in the formatting or expression. Let me help you simplify and solve it step by step:

The given equation:

6 + 2 * (3 - 2x) = 20 - (12.4x + 1.4)

Now, let's solve for 'x':

Step 1: Distribute the multiplication on both sides:

6 + 6 - 4x = 20 - 12.4x - 1.4

Step 2: Combine like terms on each side:

12 - 4x = 18.6 - 12.4x

Step 3: Move the x terms to one side by adding 12.4x to both sides:

12 + 12.4x - 4x = 18.6

Step 4: Combine the x terms on the left side:

12.4x - 4x = 18.6 - 12

8.4x = 6.6

Step 5: Divide both sides by 8.4:

x = 6.6 / 8.4

x ≈ 0.7857

So, the solution for the equation is approximately x = 0.7857.
