6x-3y=3
-2x+6y=14
Elimination:
cancel out one of the variable to =0
(6x-3y=3)2
+
-2x+6y=14
________

12x-6y=6
+
-2x+6y=14
________
10x+0y=20

2. get X by itself

10x÷10= 1x. and 20÷10=2 so x=2

3. Now plug x=2 back into the second equation to find Y

-2(2)+6y=14
-4+6y=14

4. Get Y by itself

-4+6y=14
+4. -4
6y=10
÷6. ÷6
y=10/6 (simplify the fraction to: 5/2)

Your answers should be Y=5/3 and X=2

Just plug both of these numbers into each equation for the variable other represents to check your work.

Which of the following is the proper name for the figure below?<br> 7<br> Y<br> X
VMariaS [17]

Answer:

B

Step-by-step explanation:

When you look at the triangle look at the 3 vertices. Now look at you answers given and choose one that combines all 3 vertices. You don't want your answer to contain a letter/number that represents the length of a side.

So in this case you don't want M or Y in you answer.

Your answer has to be made up of A X andT.

The only answer that uses AXT is answer B.
