Answer 1

bananas=b
strawberries=s
b=1/6s-1
2=1/6s-1
1/6s=3
s=18
She has 18 strawberries.
Hope this helps. 

Answer 2

The equation would be r = 1/6*s - 1. Put 2=r, which would be 2 = 1/6*s - 1, add 1 to both sides, the equation would be 3 = 1/6*s, multiplying by 6 would make the equation 18 = 1*s, or s. Therefore, there are 18 strawberries.
