Answer 2

Question:-

Solve the following:

$\\ \sf \: a) \: \: \frac{a}{5} + 3 = 8$

$\\ \sf \: b) \: \: \frac{3b}{7} - 1 = 5$

Solution:-

Solving question a) :

$\\ \sf \frac{a}{5 } + 3 = 8$

$\\ \sf \mapsto \frac{a + 15}{5} = 8$

$\\ \sf \mapsto \: a + 15 = 8 \times 5$

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

$\\ \sf \mapsto \: a = 25$

$\\ \sf \therefore \: a = 25$

Solving question b) :

$\\ \sf \frac{3b}{7} - 1 = 5$

$\\ \sf \mapsto \: \frac{3b - 7}{7} = 5$

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

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

$\\ \sf \mapsto \: b = \frac{42}{3}$

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

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

Answer:-

a = 25

b = 14
