Answer:

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
