To solve the equation \( 2x + 7 = -11 \), you can follow these steps:
-
Subtract 7 from both sides: \[ 2x + 7 - 7 = -11 - 7 \] This simplifies to: \[ 2x = -18 \]
-
Divide both sides by 2: \[ \frac{2x}{2} = \frac{-18}{2} \] This simplifies to: \[ x = -9 \]
So, the solution to the equation \( 2x + 7 = -11 \) is \( x = -9 \).
