77 because you have to find what’s equivalent first
(2x + 4y - 3z) + (3y + 2z + 6x) + (4z - 8x - 7y)
= 2x + 4y - 3z + 3y + 2z + 6x + 4z - 8x - 7y
= (2x + 6x - 8x) + (4y + 3y - 7y) + (-3z + 2z + 4z)
= 0 + 0 + 3z
= 3z
Answer:
Step-by-step explanation:

so these two lines intersect at x = 3 hmmmm what's the y-coordinate of the second line at that point?
so the y-coordinate of that second line is 0, so the point there is (3, 0) then.
so the first line is, a line that has a slope of 2 and passes through (3, 0).
5.2 < x < 5.5
square
5.2² < x² < 5.5²
27.04 < x² < 30.25
Pick any number for between 27.04 and 30.25 for x², as long as it's not a perfect square. So you could pick 30.
x² = 30
x = √30 → irrational number between 5.2 and 5.5
