Answer 2

Step-by-step explanation:

$5x - 4y = 4 \: \: \: \: \: ....(1)$

$x - 12y = 20 \: \: \: \: \: ....(2)$

Multilpy Equation 1 by 3

It becomes

$15x - 12y = 12 \: \: \: \: ....(3)$

Subtract equation 2 from 3

$14x = - 8$

or

$x = \frac{ - 4}{7}$

Put the value of x in any of the equation 1 or 2 and obtain y.

Hope it helps :-)
