What is the value of the x variable in the solution to the following system of equations?

4x + y = 8
x − 2y = 2

0

2

There is no x value as there is no solution to this system

x can be any value as there are infinitely many solutions to this system

Wait..there is a solution.  X=2, Y=0

anonymous · Answer

x=2 because y=0

shane_b · Answer

Yes, so the answer from the choices is "2"

anonymous · Answer

so the value of x is 2? :)

anonymous · Answer

teehee thank you guys..! :)

anonymous · Answer

you find the value of y first by getting x to cancel out, which you do by multiplying the second equation by -4. this will make x cancel out, and also the constant will cancel as well. this leaves you with 8y+y=0. add the y's, divide, and you get 0. substitute 0 into one of the equations, and 2 will be your value for x.
