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?
23x + x = 30, 2+23x + 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
3x2 + x = 30
4x = 32
Take a look at your arithmetic. The equations don't add up.

so it should be 3x2 + x = 30
3x2+2+x = 30+2
3x+x = 32
4x = 32
4x/4 = 32/4
x=8

so it should be 3x2 + x = 30
3x2+2+x = 30+2
3x+x = 32
4x = 32
4x/4 = 32/4
x=8
