X = 3
y = -1 

get the x or y by itself first (second eq. is easier)
So, x + 2y = 1
          -2y     -2y
Now we get: 
x = -2y +1 Plug it into the other equation.

2x + 3y = 3
2(-2y +1) + 3y = 3
-4y + 2 + 3y = 3
-1y +2 = 3
+1y -3    -3  +1 y

y = -1 (plug into either eq to get x)

<span>x + 2y = 1
</span>x+2(-1) = 1
x-2=1
 +2  +2

x = 3

blondinia [14]

Answer:

We choose D.

Step-by-step explanation:

The question is which statement is true?

A. 33% of the people surveyed were vegetarian and though saving energy was not important

=> It is wrong because we do not know the total number of people who were surveyed.

B. This statement is wrong, because we also have 26% non - vegetarian though saving energy was not important

C. This statement is wrong, because there are 38% non - vegetarian though saving energy was not important and only 26% non - vegetarian though saving energy was very important

D. True because there are 36% non - vegetarian though saving energy was somewhat important while there are 17% vegetarian think so. Hence, a person who was not a vegetarian was morel likely than a vegetarian to think that saving energy is somewhat important

=> We choose D.
