    Step-by-step explanation:

    Just as a hint. On this editor, you have to use brackets a lot. We cannot be certain what you mean. I'm going to interpret the question one way, but there are others.

    √ (5x - 7) = √ (3x + 5)

    Square both sides.

    (√ (5x - 7)) ^2 = (√ (3x + 5)) ^2

    5x - 7 = 3x + 5

    Add 7 to both sides.

    5x - 7 + 7 = 3x + 5 + 7

    Combine

    5x = 3x + 12

    Subtract 3x from both sides.

    5x - 3x = 3x - 3x + 12

    Combine

    2x = 12

    Divide by 2

    2x/2 = 12/2

    x = 6
