Answer:
x=-6, y=0
Step-by-step explanation:
it's impossible to fully solve an equation where 2 variables are unknown. So we have to make it equal to 1 set. to do this, we have to think logically.
if y=x+6, then that means wherever it says y, we can put x+6. because x+6=x+6, right? so we plug x+6 into the second equation and get.
x+6=0.5x+3
to solve for x we subtract 6 from one side and 0.5 from the other and get
0.5x=-3
then we multiply both sides by 2 to make be a whole number
x=-6
now we just plug this into either equation. because the first one is easier, we can just set it up as
y=(-6)+6
which means y=0
