18n-12n-3n=186

To solve the equation \( 18n - 12n - 3n = 186 \), first, combine the like terms on the left side: \[ (18n - 12n - 3n) = 186 \] Calculating the left side: \[ (18 - 12 - 3)n = 186 \] \[ 3n = 186 \] Now, divide both sides by 3 to solve for \( n \): \[ n = \frac{186}{3} = 62 \] So the solution is: \[ n = 62 \]
