    Step-by-step explanation:

    Number of blue beads = x

    Number of red beads = x + 8

    Total beads = 30

    x + x+8 = 30

    2x + 8 = 30

    Solution:

    Subtract 8 from both sides

    2x + 8 - 8 = 30 - 8

    2x = 22

    Divide both side by 2

    2x/2 = 22/2

    x = 11

    Number of blue beads = 11

    Number of red beads = 11 + 8 = 19
