Answer:
C aka the third one
Step-by-step explanation:
So the problem is asking you to combine equations, in this case the Y factor will cancel out so you will be left with the X factor and the total after you add both of the totals together,
6x-4y=16
5x+4y=6
6x-5x=x
16+6=22
x=22
Answer:
I have no idea what are you talking about......
(23 x 2) - 12 = x
We need 2 cookies per student, so multiply the amount of students by 2. which is 23 x 2. Then because you already baked 12 subtract 12 from the original amount you needed to bake. Which is 46 - 12. Oh and if you wanted the answer, it's 34.
