Question

I WILL FAN AND MEDAL!!!
What is the value of the x variable in the solution to the following system of equations?

3x − 6y = 3
7x − 5y = −11

−2

−3

x can be any number as there are infinitely many solutions to the system.

There is no x value as there is no solution to the system.

Answer 1

the answer is -2, let me explain why

Answer 2

Answer 3

I know the proccess I just wanted to see if the answer I had was right.

Answer 4

multiply 3x - 6y = 3 by -7:
-7(3x - 6y) = -7(3)
-21x + 42y = -21

and then i will multiply 7x - 5y = -11 by 3:
21x - 15y = -33

add them:
21x - 21x - 15y + 42y = -21 - 33
27y = -54
y = -2

Answer 5

Thanks! @AwesomeB

Answer 6

the answer is -3.

Answer 7

I'm confused now...

Answer 8

yw and @ranjeet619 the correct answer is -2 check my work

Answer 9

wait a second she is asking the value of the x-variable, not the y-variable. SO you are incorrect @AwesomeB

Answer 10

the y-variable is correct, but the x-variable is undefinded as of now. @ranjeet may be correct, but i will prove for sure

Answer 11

3x-6(-2)=3
3x+12=3
-12 -12
3x=-9
/3 /3
x=-3

7x-5(-2)=-11
7x+10=-11
-10 -10
7x=-21
/7 /7
x=-3

Answer 12

therefore, x=-3

Answer 13

the coordinates are (-3-2)
@ranjeet619 was correct my fault

Answer 14

does that make sense @aleximhappy08 ?

Answer 15

(-3,-2)

Answer 16

right but the question is asking what the x-variable is, and that is -3. That is why you MUST show your work before you provide an answer! I hope you learned your lesson @AwesomeB

Answer 17

I read the question wrong and I thought she was looking for y

Answer 18

Thanks guys!

Answer 19

anytime just hit me up if u need help in the future @aleximhappy08
