Answer 2

$hii \: \\ friends \\ \\ good \: evening \\ \\ \\ \\ \\ 2x - (2a + 5)y = 5 \\ \\ 2x - (2x + 5)y = 5 \\ \\ \\ \\ 2x - 7x \: y = 5 \\ \\ \\ x = 5 \: y = 5 \\ \\ \\ x = \frac{5}{5} \\ \\ \\ x = 1 \: is \: the \: value \: of \: a \\ \\ \\ \\ \\ \\ - (2b + 1)x - 9y = 15 \\ \\ - 3bx - 9y = 15 \\ \\ 9 + 3 = 15 \\ \\ 12 = 15 \\ \\ 12 \div 15 \\ \\ \\ = \frac{4}{5} \\ \\ = 1 \: is \: the \: value \: of \: b$
