    x = 1.75y + 0.25z

    Step-by-step explanation:

    Simplifying

    4x + - 7y = z

    Solving

    4x + - 7y = z

    Solving for variable 'x'.

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

    Add '7y' to each side of the equation.

    4x + - 7y + 7y = 7y + z

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

    4x + 0 = 7y + z

    4x = 7y + z

    Divide each side by '4'.

    x = 1.75y + 0.25z

    Simplifying

    x = 1.75y + 0.25z
