I think y=0 because 6 multiple by 0 is 0 then x= 6 hope this helps might want to check my work to
Parentheses
Exponents
Multiply/Divide
Add/Subtract
<span>x+2 = -x+6
</span>2x+2 = 6
2x = 4
x = 2
Im pretty sure it would be 10??? if you are putting it as a subtraction problem if not i would try wording it more clearly
