Question:-

Solve the following:


\\ \sf \: a) \: \: (a)/(5) + 3 = 8


\\ \sf \: b) \: \: (3b)/(7) - 1 = 5

Solution:-

Solving question a) :


\\ \sf (a)/(5 ) + 3 = 8


\\ \sf \mapsto (a + 15)/(5) = 8


\\ \sf \mapsto \: a + 15 = 8 * 5


\\ \sf \mapsto \: a = 40 - 15


\\ \sf \mapsto \: a = 25


\\ \sf \therefore \: a = 25

Solving question b) :


\\ \sf (3b)/(7) - 1 = 5


\\ \sf \mapsto \: (3b - 7)/(7) = 5


\\ \sf \mapsto3b - 7 = 5 * 7


\\ \sf \mapsto3b = 35 + 7


\\ \sf \mapsto \: b = (42)/(3)


\\ \sf \mapsto \: b = 14


\\ \sf \therefore \: b = 14

Answer:-

a = 25

b = 14
