first set the first equation equal to x
subtract 2y from both sides
x=27-2y now plug this in to the other equation
2(27-2y)+3y=46 distribute
54-4y+3y=46 --> 54-y=46 now subtract 54 from both sides -y=-8 --> D)y=8
If you weren't asked to show work you could just plug the choices given into the equation

Answer:
C(C^3 + 8C^2 -3C -7)
Step-by-step explanation:
(-3C^4-5C^2-7C)+(4C^4+8C^3+2C^2)
(-3C^4 +4C^4)+8C^3 + ( -5C^2 +2C^2) -7C [Combine like terms]
C^4 + 8C^3 -3C^2 -7C [Simplify]
C(C^3 + 8C^2 -3C -7) [Isolate 1C from the rest]
The subjects in the experiment are given as follows:
b) the two AP Statistics curricula.
<h3>What are the subjects of an experiment?</h3>
The subjects of an experiment are the hypotheses which are studied in the experiment.
For this problem, we are testing hypotheses involving two forms of the curriculum, hence the correct option is given by:
b) the two AP Statistics curricula.
