Last month dory biked 11 times as many miles as karly. together they biked a total of 156 miles. how many miles did dory bike last month ?

I think You have to divide 159 by 11, and that would make you get 14.

11x + x = 156 12x = 156 X=13 X is distance karly biked. Dory biked 11 times as far as karly so she biked 11x miles. X=13 so Dory biked 11*13 miles = 143 miles
