    Answer:

    B- one solution: (1,-4)

    Step-by-step explanation:

    (1,-4)

    y = -6x +2

    -4 = -6(1) +2

    -4 =-4

    (1,-4)

    -12x – 2y = -4

    -12(1) -2(-4) = -4

    -12 + 8 =-4

    -4 = -4

    if you put the value x and y into both equation you can find the solution

    Answer:

    Hi there!

    The correct answer is: D. Infinite number of solutions

    Step-by-step explanation:

    in this case you can use the substitution method to solve these linear equations

    since y = -6x +2 you can plug this into the equation -12x -2y = -4

    -12x – 2(-6x +2) = -4 this comes out to be -12x + 12x -4 = -4

    then you simplify down to 0x=0
