    x = - 4

    Step-by-step explanation:

    Simplifying

    5x + - 4 = 7x + 4

    Solving

    -4 + 5x = 4 + 7x

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

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

    -4 + 5x + - 7x = 4 + 7x + - 7x

    Combine like terms: 5x + - 7x = - 2x

    -4 + - 2x = 4 + 7x + - 7x

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

    -4 + - 2x = 4 + 0

    -4 + - 2x = 4

    Add '4' to each side of the equation.

    -4 + 4 + - 2x = 4 + 4

    Combine like terms: - 4 + 4 = 0

    0 + - 2x = 4 + 4

    -2x = 4 + 4

    Combine like terms: 4 + 4 = 8

    -2x = 8

    Divide each side by '-2'.

    x = - 4

    Simplifying

    x = - 4
