Naomi has 50 red beads and white beads. The number of red beads is 1 more than 6 times the number of white beads.
How many red beads does Naomi have?

Let w = white beads. Solve for w and then find the number of red beads.
w + 6w + 1 = 50
7w = 50  1
7w = 49
w = 49 / 7
w = 7
She has 7 white beads.
7 * 6 = 42 red beads
Check:
7 + 1 + 42 = 50 
w+6w+1=50
7w=501
7w=49
w=49/7
w=7
she has 7 white beans
7*6=42red beans
check
7+1+42=50
