(2n + 4) 3/14
= 2 n(3/14) + 12/14
= 1
so
6 n + 12 = 14
6 n = 2
n = 1/3
=================
check
=================
2 * 1/3 = 2/3
2/3 + 4 = 2/3 + 12/3 = 14/3
14/3 * 3 = 14
and sure enough 14/14 = 1
= 2 n(3/14) + 12/14
= 1
so
6 n + 12 = 14
6 n = 2
n = 1/3
=================
check
=================
2 * 1/3 = 2/3
2/3 + 4 = 2/3 + 12/3 = 14/3
14/3 * 3 = 14
and sure enough 14/14 = 1
