(0,infinity) is the answer for that one I think... because y is undefined at x=0 so it’s not included in the interval so it is (0,infinity) with a parenthesis at 0 because it is not included in the interval
2x + 3z = 12 <span>and z = -2, then x=6
</span><span>
2x + 3(-2) = 12
2x = 18
x = 9
answer
False </span>
