Hey there ‼
n/4 – 5 = n/6 + 1/2
( n – 20 ) / 4 = ( n + 3 ) / 6
6 ( n – 20 ) = 4 ( n + 3 )
6n – 120 = 4n + 12
6n – 4n = 120 + 12
2n = 132
n = 132 / 2
n = 66
n/4 – 5 = n/6 + 1/2
( n – 20 ) / 4 = ( n + 3 ) / 6
6 ( n – 20 ) = 4 ( n + 3 )
6n – 120 = 4n + 12
6n – 4n = 120 + 12
2n = 132
n = 132 / 2
n = 66
