    Answer: v = - 4

    Step-by-step explanation:

    Simplifying

    4v + - 7 = 5 + 7v

    Reorder the terms:

    -7 + 4v = 5 + 7v

    Solving

    -7 + 4v = 5 + 7v

    Solving for variable 'v'.

    Move all terms containing v to the left, all other terms to the right.

    Add '-7v' to each side of the equation.

    -7 + 4v + - 7v = 5 + 7v + - 7v

    Combine like terms: 4v + - 7v = - 3v

    -7 + - 3v = 5 + 7v + - 7v

    Combine like terms: 7v + - 7v = 0

    -7 + - 3v = 5 + 0

    -7 + - 3v = 5

    Add '7' to each side of the equation.

    -7 + 7 + - 3v = 5 + 7

    Combine like terms: - 7 + 7 = 0

    0 + - 3v = 5 + 7

    -3v = 5 + 7

    Combine like terms: 5 + 7 = 12

    -3v = 12

    Divide each side by '-3'.

    v = - 4

    Simplifying

    v = - 4
