Being X the number of elephant ears Preston ate, X - 2 is the number Vincent ate, thus

X + X - 2 = 8

Joining like terms:

2X - 2 = 8

Adding 2 to each side of the equation

2X - 2 + 2= 8 + 2

Operating

2X = 10

Solving for X

X = 10 / 2 = 5

Thus, Preston ate 5 elephant ears and Vincent ate 5 - 2 = 3 ears
