If y=3 and 2x+4y=8 what does x equal?

1 answer:

7 0

If y equaled 3, then we would plug 3 into the y spot on the equation. Therefore it would be 2x+4(3)=8. Now just solve.

2x+4(3)=8
2x+12=8
2x-12=8-12
2x=-4
2x/2=-4/2
X=-2

Hope this helped!

Amanda [17]

Well, negatives are less than zero, and the greater the number the less it is, or in this case colder, so we know that the first two are -19, and -10, then comes 0, and increases from there. So, the answer would be B. (-19, -10, 0, 15, 28)
