To solve the equation \( 2x + 3 = x - 7 \), follow these steps: 1. Subtract \( x \) from both sides: \[ 2x - x + 3 = -7 \] This simplifies to: \[ x + 3 = -7 \] 2. Next, subtract 3 from both sides: \[ x = -7 - 3 \] This gives: \[ x = -10 \] So, the solution is: \[ \boxed{-10} \]

To solve the equation \( 2x + 3 = x - 7 \), follow these steps:

Subtract \( x \) from both sides: \[ 2x - x + 3 = -7 \] This simplifies to: \[ x + 3 = -7 \]
Next, subtract 3 from both sides: \[ x = -7 - 3 \] This gives: \[ x = -10 \]

So, the solution is: \[ \boxed{-10} \]
