Answer 2

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

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ 7 ( y + 4) - 9 ( y - 5) = 5( y + 9)}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ 7y + 28 - 9y + 45 = 5y + 45}}$

⠀⠀

$: \implies\: \sf{\bold{ -2y + 73 = 5y + 45}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ 5y + 2y = 73 - 45}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ 7y = 28}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ y =\dfrac{28}{7}}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ y = 4}}$
