Please help ASAP thank you

Question 2

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) :

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

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

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

$\\ \sf \mapsto3b = 35 + 7$

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

$\\ \sf \mapsto \: b = 14$

$\\ \sf \therefore \: b = 14$

a = 25

b = 14

Question 3

Answer:

A) a = 25

B) b = 14
