Answer 2

$\sf{\red{\boxed{\bold{Solution}}}}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ \dfrac{7x - 2}{3 + 4} = 15 }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ \dfrac{7x-2}{7} = 15 }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ 7x - 2 = 15\times 7 }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ 7x - 2 = 105 }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ 7x = 105 + 2 }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ 7x = 107 }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ x = \dfrac{107}{7} }}$

⠀⠀

$\sf:\implies \: {\bold{ y = 15\dfrac{2}{7} }}$
