1/2 = q + 2/3
and
p - 3 1/6 = -18.73

please help, im giving 20 points

see below

Step-by-step explanation:

1/2 = q + 2/3

Subtract 2/3 from each side

1/2 -2/3 = q+2/3-2/3

Getting a common denominator of 6

3/6 - 4/6 = q

-1/6 =q

p - 3 1/6 = -18.73

Add 3 1/6 to each side

p - 3 1/6 + 3 1/6 = -18.73 + 3 1/6

p = -18 73/100 + 19/6

Get a common denominator

p =- 5619/300 + 950/300

  = -4669/300

=-15 169/300
