4. 8,10 ( like and follow for efforts taken)

Answer 2

Answer:

$2x + 3y = 46 \\ 3x + 5y = 74 \\ \\ = multiplying 3in \: equation \: 1 \\ and \: 2i \ n \: equation \: 2 \\ 6x + 9y = 138 \\ 6x + 10y = 148 \\ then \: differnce \: \\ = - y = - 10 \\ = y = 10 \\ then \: putting \: these \: value \: in \: equation \: \: 1 \\ = 2x \: + 3y = 46 \\ = 2x + 3 \times 10 = 46 \\ = 2x + 30 = 46 \\ = 2x = 46 - 30 \\ = 2x = 16 \\ = x = 8 \\ = (x.y) = (8.10)$
