    Answer:

    C. x = 3

    Step-by-step explanation:

    Step 1:

    – 6x + 19 = x – 2

    Step 2:

    – 7x + 19 = – 2

    Step 3:

    – 7x = – 21

    Step 4:

    21 = 7x

    Answer:

    Answer:

    x=3

    Step-by-step explanation:

    Move the variables to the left-hand side and change its sign. Move constant to the right-hand side and change its sign.

    -6x-x=-2-19

    Collect like terms

    -7x=-21

    Divide both sides of the equation by -7

    x=3
