(1) 2 of one step equations 
x - 23 = 8
x - 23 + 23 = 8 + 23
x = 31
n + 2 = 9
n + 2 - 2 = 9 - 2
n = 7
(2) 2 equations with fractions 
3/4 (x + 3) = 9
4 [ 3/4 (x + 3) ] = 4[9]
3 (x + 3) = 36
3x + 9 - 9 = 36 - 9
3x/3 = 27/3
1/3 x 3/4
cross multiply 
so 3/12 and simplify which makes it
1/4
(3) distributive property
3(2 + 4) = (3 • 2) + (3 • 4) 
3(6) = 6 + 12
18 = 18

2/5 or 40% of a bottle.
Step-by-step explanation:
A bottle can hold 5 milliliters of perfume. You only have 2 milliliters. Divide 2 with 5: 
(2/5)(20/20) = 40/100 = 0.40 = 40%
