The correct answer is y = 11
because:
2y + 7 = 3y − 4
−y + 7 =−4
Subtract 7 from both sides.
−y + 7 − 7 = − 4 − 7
−y = −11
Divide both sides by -1.
y = 11
So we have 2 variables here: tacos and orders of nachos.
When we translate the paragraphs into equation:

Now, in this situation we can make use the elimination method by converting 3n to -27n.

Add both equations:

So we find that one taco costs $2.75.
We can plug this into any of the first two equations to find n:

So one order of nachos cost $1.40.
Answer:
Step-by-step explanation:
Hello
please find attached the graph
you can notice that 
(a) from the graph we can say that there is no maximum and one minimum in x = 3
and then f(3) = 0 so o is the minimum of f
(b) vertex is (3,0)
(c) x = 3 is an axis of symmetry
(d) as
the root is 3
(e) y=9 for x = 0 so the y-intercept is 9

Question:
Solution:
The solution to a system of linear equations is where the graphs of each linear equation intersect. In this case, we can see that the lines intersect at the point:
(-3,2)
thus, the correct answer is (-3,2).
