Answer 1

Answer:

$\huge \underline \red{★ Answer❀✿°᭄★}$

$x ^{2} -y ^{2} +3y-5 \: is \: sum \: of\: equation \\ and \: one \: of \: them \: is2y ^{2} +2x-y-10$

$to \: find \: the \: other \: one \: substract \: 2y^{2} +2x-y-10 \: from \: x ^{2} -y ^{2} +3y-5$

$⇒ \: {x}^{2} - {y}^{2} + 3y - 5 - (2 {y}^{2} + 2x - y - 10) \\ \\ ⇒ \: {x}^{2} - {y}^{2} + 3y - 5 - 2 {y}^{2} - 2x + y + 10 \\ \\ ⇒ \: {x}^{2} - 3y + 4y + 5$
