Solution

Solution Steps

To solve for $ x $ in the given equation, we need to follow these steps:

Distribute the constants inside the parentheses.
Combine like terms on both sides of the equation.
Isolate the variable $ x $ by moving all terms involving $ x $ to one side and constant terms to the other side.
Solve for $ x $.

Step 1: Distribute the Constants

Distribute the constants inside the parentheses: \[ 5.5(6 - x) + 27 = 100 - 2.5(3x + 20) \] \[ 5.5 \cdot 6 - 5.5x + 27 = 100 - 2.5 \cdot 3x - 2.5 \cdot 20 \] \[ 33 - 5.5x + 27 = 100 - 7.5x - 50 \]

Step 2: Combine Like Terms

Combine like terms on both sides of the equation: \[ 60 - 5.5x = 50 - 7.5x \]

Step 3: Isolate the Variable $ x $

Move all terms involving $ x $ to one side and constant terms to the other side: \[ 60 - 50 = -7.5x + 5.5x \] \[ 10 = -2x \]

Step 4: Solve for $ x $

Solve for $ x $: \[ x = \frac{10}{-2} \] \[ x = -5 \]
