Answer:
Blank 1: is (two times/twice) as much as
Blank 2: is the same as
Blank 3: are
Step-by-step explanation:
Here, you don't necessarily need to solve the systems; just look & see if you notice anything. The first equation in system 2 has all of its terms multiplied by 2 compared to system 1. The second equation is the same in system 2 as in system 1. Since the same factor applies for both sides (for both equations), we can deduce the equations are equivalent.
So the sentence should go like this: The first equation in the second system is (two times/twice) as much as in the first system, and the second equation in the second system is the same as in the first system. Thus, the systems are equivalent.
