Answer:

King size(x): 3

Regular size(y): 2

Steps:

System of Equations:

x+y = 5

3.75x+1.75y = 14.75

Multiply 3.75 on all sides.

3.75x+3.75y = 18.75

3.75x+1.75y = 14.75

Subtract top and bottom

            2y  = 4

            /2      /2

             y   =  2

After you know regular size amount, figure out king size ----3.

5-2 = 3.
