Answer 1

$\mathbb{HELLO \: \: DEAR,}$

$\mathbb{GIVEN \: \: THAT:-\:Y} = -2$

$\mathbb{PUT \: \: IN \: \: THE \: \: GIVEN \: \: EQUATION}$

$\bf7(-2)^2 - 3(-2) - k = 35\\ \\ \bf7(4) + 6 - k = 35 \\ \\ \bf34 - k = 35\\ \\ \bf \: k = 34 - 35 \\ \\ \bf \: k = - 1$

$\mathbb{\underline{I \: \: HOPE \: \: ITS \: \: HELP \: \: YOU \: \: DEAR, \: \: THANKS}}$
