Questions: 7x+7=2x-8

Transcript text: $7x+7=2x-8$

Solution

Step 1: Move all $ x $-terms to one side

Subtract $ 2x $ from both sides of the equation: \[ 7x - 2x + 7 = -8 \] Simplify: \[ 5x + 7 = -8 \]

Step 2: Move constant terms to the other side

Subtract $ 7 $ from both sides: \[ 5x = -8 - 7 \] Simplify: \[ 5x = -15 \]

Step 3: Solve for $ x $

Divide both sides by $ 5 $: \[ x = \frac{-15}{5} \] Simplify: \[ x = -3 \]

$\boxed{x = -3}$
