2x − y = 6 4x − 2y = 12 0 4 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.

Question

2x − y = 6 4x − 2y = 12   0   4   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.

anonymous · Answer

I didn't get you what is it after 4x-2y=12

xochital · Answer

sorry, that's not very clear... 

What is the value of the x variable in the solution to the following system of equations?
2x − y = 6
4x − 2y = 12

 0

 4

 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.

anonymous · Answer

divide equation 2 by 2,u wil get same eqation

anonymous · Answer

no use in solving this 1

xochital · Answer

so no x value?

anonymous · Answer

for 2 variables,you need to "different" eqations to solve it

anonymous · Answer

right

xochital · Answer

thanks! :) can you help me with a few more?

anonymous · Answer

sure

The three Math Idol judges have been eliminating contestants all day! The number of one-step equations and two-step equations who have been eliminated today is equal to 1150. If three times the number of one-step equations minus twice the number of two-step equations is equal to 1300, how many one-step equations eliminated today?

 430

 720

 1150

 1300

anonymous · Answer

hold on

anonymous · Answer

equations are easy

anonymous · Answer

1st is x+y=1150
and 2nd one is
3times x minus 2 times y
that's 3x-2y=1300
now solve these equations

anonymous · Answer

got it?

xochital · Answer

hold on...

badhi · Answer

For the first question you've mentioned I have to make a correction.You have understood that there is one equation, ie.

$$2x-y=6$$ 

take $$y=t \implies x=\frac{6+t}{2}$$

so, for each value t, there is infinite number of set of solutions. So, no solution for x is not the answer

xochital · Answer

oh okay, thank you :)

anonymous · Answer

by the way
when you solve
answer comes 720
cross check~

anonymous · Answer

:)

xochital · Answer

lol okay thanks, i just got it!  :)

anonymous · Answer

good <3

xochital · Answer

how about...
What is the value of the y 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

anonymous · Answer

multiply eq. 1 by 7 and 2 by 3,
then subtract both,x will get eliminated

anonymous · Answer

y=-2
and x=-3
that's right,you got it?

xochital · Answer

yes! thank you again :D

anonymous · Answer

you are welcome :)

anonymous · Answer

any other?

xochital · Answer

What is the value of the x variable in the solution to the following system of equations?

4x + 2y = 12
  x – y = 3   

 0

 −3

 3

 2

anonymous · Answer

multiply equation 2 by 2 and add both equations
you will get x

anonymous · Answer

which is 3

xochital · Answer

lol okay i thought so. that's it, thank you so much :)

anonymous · Answer

no problem miss. :)
