Plzz help

Answer 1

T = Terrill's age
C = Cranston's age

Using the info provided:
C + 4 = T
T + 2 = 2C

Isolate variable:

T = 2C - 2

Your two equations:
C + 4 = T
T = 2C - 2

Set them equal to eachother:
C + 4 = 2C - 2

Solve for C

Cranston's Age = 6

Solve for T using your equation:

Terrill's age = 10
