X = mary's shells
g = 1 1/4x + 5
n = 1 1/2x+ 1
g = n
1 1/4x + 5 = 1 1/2x + 1
5/4x + 5 = 3/2x + 1...multiply by common denominator of 4, this will get rid of fractions...however, this is optional...u can work with fractions if u wish.
5x + 20 = 6x + 4
5x - 6x = 4 - 20
-x = - 16
x = 16....so Mary has 16 shells

Answer:
11 33/35
Step-by-step explanation:
5 3/7 = 5 × 7/7 + 3/7 = 35 + 37 = 38/7
38/7 ÷ 5/11 = 38/7 × 11/5 = 38 × 11/7 × 5 = 418/35
418/35 = 11 33/35
