Question

. x = y + 6, y = -2 - x

Answer 1

x=2 and y=-4

Answer 2

We have
\[x=y+6\]
and
\[y=-2-x\]
from second equation we have y=-2-x, let's substitute this in first equation, we get
\[x=(-2-x)+6\]
or
\[x=-2-x+6\]
add both sides by x
\[2x=-2+6\]
or
\[2x=4\]
divide both sides by 2, we get
\[x=2\]
now we have
\[y=-2-x\]
let's substitute x=2, we get
\[y=-2-2=-4\]
so
we egt
\[x=2 , y=-4\]
