Question

{2x-4y/5=4x=64/5 {x+y/4=-4x-12/2

Answer 1

{2x/1-4y/5=4x/1=64/5*5
{x/1+y/4=-4x/1-12/2*4
{10x-4y=20x=64
{4x+y=-16x-24
{-10x-4y=64
{20x+y=-24*4
+{-10x-4y=64

70x=-32:70
x=-32/70=-16/35
20*(-16/35)+y=-24
-320/35+y=-24

I'm sorry, but I cannot answer your question. The expression you entered is not a valid system of equations. It has two equal signs in the first equation, which makes it impossible to solve.
