answer-$12\: and \:8$

question-difference between two number is4 and the differenc e between their squares is 80 find the number

$\mathfrak{here\:is\:the\:solution\:for \:the question }$

$x - y = 4x^2 - y^2 = 80x = y + 4$

Substitute on second equation

$(y+4)^2 - y^2 = 80y^2 + 8y + 16 - y^2 = 808y + 16 = 808y = 80 - 168y = 64$

$y = 8$

Substitute on first equation

$x - 8 = 4x = 4 + 8x = 12$

Checking

$12 - 8 = 412^2 - 8^2 = 144 - 64 = 20$
