-4x + 3(2x - 5) = 31 (use distributive property to remove parentheses)
-4x + 6x - 15 = 31 (combine like terms)
2x - 15 = 31 (add 15 to both sides)
+15 +15
2x = 46 (divide both sides by 2)
x = 23
This is the number of combinations of 5 from 11.
11C5 = 11! / 5!6!
a quick way to work it out is (11*10*9*8*7) / (5*4*3*2*1)
= 462 answer
