n/5+5/7=2/3
7n+25/35= 2/3
7n+25=2/3*35
7n +25=70/3
7n = 70/3-25
7n = 70-75/3
7n = -5/3
n = -5/21.
hope helped !

N/5 + 5/7 = 2/3
N/5 = 2/3 - 5/7
N/5 = (2 × 7 - 5 × 3)/3 × 7
N/5 = (14 - 15)/21
N/5 = -1/21
N = -5/21
Hence N = -5/21
N/5 = 2/3 - 5/7
N/5 = (2 × 7 - 5 × 3)/3 × 7
N/5 = (14 - 15)/21
N/5 = -1/21
N = -5/21
Hence N = -5/21
