The Deep Dive
To solve the equation \( 11n + 23 = 6n - 47 \), we first want to get all terms involving \( n \) on one side and constant terms on the other. Start by subtracting \( 6n \) from both sides to get: \[ 11n - 6n + 23 = -47 \] This simplifies to: \[ 5n + 23 = -47 \] Next, subtract 23 from both sides: \[ 5n = -47 - 23 \] Which gives: \[ 5n = -70 \] Finally, divide both sides by 5: \[ n = -14 \] So the solution to the equation is \( n = -14 \). Fun fact: negative numbers have a fascinating history, once considered controversial in mathematics! Some ancient cultures didn’t recognize them at all!
