    x = - 10

    Step-by-step explanation:

    Given

    5x + 3 = 4x - 7 (subtract 4x from both sides)

    x + 3 = - 7 (subtract 3 from both sides)

    x = - 10

    5x+3=4x-7

    Move 3 to the other side

    Sign changes from + 3 to - 3

    5x+3-3 = 4x-7-3

    5x = 4x-10

    Move + 4x to the other side

    Sign changes from + 4x to - 4x

    5x-4x = - 10

    1x = - 10

    Divide by 1

    1/1x = - 10/1

    x = - 10

    Answer : x = - 10
