Answer 2

Let's solve the equation step by step:

Given equation: -2 = -9 - 2 * (-2x + 1)

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

-2 = -9 + 4x - 2

Step 2: Combine like terms on the right side:

-2 = -11 + 4x

Step 3: To isolate the variable term (4x) on one side of the equation, add 11 to both sides:

-2 + 11 = 4x

Step 4: Simplify the left side:

9 = 4x

Step 5: Now, to solve for x, divide both sides by 4:

x = 9/4

The solution for the equation is x = 9/4 or 2.25.
