Answer 2

Step-by-step explanation:

$4x - 3y = - 10 \\ 8x - 2y = 20 \\ multiply \: eq1 \: by \: 2 \: and \: eq \: by \: 3 \\ equation \: become \\ 8x - 6y = - 20 \\ 24x - 6y = 60 \\ now \: substact \: equation \\ it \: become \\ - 16x = - 80 \\ x = \frac{ - 80}{ - 16} \\ x = 5 \\ now \: put \: this \: value \: in \: eq \: 1 \\ 4 \times 5 - 3y = - 10 \\ 20 - 3y = - 10 \\ - 3y = - 10 - 20 \\ - 3y = - 30 \\ y = \frac{ - 30}{ - 3} \\ y = 10 \\ hence \: x = 5 \: and \: y = 10$
