    x = - 10

    x = 7

    Step-by-step explanation:

    2 (x+3) = x - 4

    2x + 6 = x - 4

    2x - x = - 4 - 6

    x = - 10

    4 (5x-2) = 2 (9x+3)

    20x - 8 = 18x + 6

    20x - 18x = 6 + 8

    2x = 14

    x = 7

    have a nice day : D

    2x (x + 3) = x - 4

    2x + 6 = x - 4

    2x - x - 4

    X = - 10

    4 (5x + - 2) = 2 (9x + 3)

    20x - 8 = 18x + 6

    20x - 18x = 6 + 8

    2x/2 = 14/2

    X = 7
