Answer 2

Given :

$\\ \bf \: (i) \: \frac{y}{8} = \frac{9}{14}$

Solution :

$\\ \implies \sf \: \frac{y}{8} = \frac{9}{14} \\ \\ \implies \sf \: 14y = 72 \\ \\ \\ \implies \sf \: y = \frac{72}{14} = \frac{36}{7} \\ \\ \implies \boxed{ \sf{y = \frac{36}{7} }}$

$\bf \: (j) \: 180k = - 45$

$\implies \sf \: 180k = - 45 \\ \\ \implies \sf \: k = \frac{ - 45}{180} = - \frac{9}{36} = \frac{ - 1}{4} \\ \\ \\ \implies \boxed{ \sf{k = \frac{ - 1}{4} }}$

Question (2)

$\bf \: (a) \: 2l + 18 = - 37$

$\implies \sf \: 2l + 18 + 37 = 0 \\ \\ \implies \sf \: 2l + 55 = 0 \\ \\ \implies \boxed{ \sf{l = \frac{ - 55}{2} }}$

$\bf \: (b) \: 56 + 6t = 44$

$\implies \sf \: 56 + 6t = 44 \\ \\ \implies \sf \: 6t = 44 - 5 6 \\ \\ \implies \sf \: 6t = - 12 \\ \\ \implies \boxed{ \sf{t = - 2}}$

$\bf \: (c) - 71 + 10r = 179$

$\implies \sf \: - 71 + 10r - 179 = 0 \\ \\ \implies \sf \: 10r = 250 \\ \\ \implies \boxed{ \sf{r = 25}}$

$\\ \bf \: (d) \: \frac{13d}{4} = - 65 \\ \\ \implies \sf \: \frac{13d}{4} = - 65 \\ \\ \implies \sf \: \frac{d}{4} = - 5 \\ \\ \implies \boxed { \sf{d = - 20}}$
