I need help with a word problem. Stella's sock drawer contains 30 pairs of socks. There are 3 times less 2 the number of pink socks than blue socks. How many pairs of pink socks and blue socks does Stella have?
2-3x + x = 30, 2+2-3x + x = 30 +2,
4x/4 = 32/4, x=8, 8 blue & 22 pink. Did I set this up correctly and is answer correct?

    the answer is correct, but your equation is wrong

    3x-2 + x = 30
    4x = 32

    Take a look at your arithmetic. The equations don't add up.

    so it should be 3x-2 + x = 30
    3x-2+2+x = 30+2
    3x+x = 32
    4x = 32
    4x/4 = 32/4
    x=8

  • MaTh -

    so it should be 3x-2 + x = 30
    3x-2+2+x = 30+2
    3x+x = 32
    4x = 32
    4x/4 = 32/4
    x=8
