A) 6x -5y = 5
B) 3x + 5y = 4
Adding the equations:
9x = 9
x = 1
A) 6*1 -5y = 5
A) 6 - 5 = 5y
A) 5y = 1
y = 1/5 = .2
Answer:
Pam 6
Tia 8
Veronica 11
Lily 15
Step-by-step explanation:
Tia's age = 8
Pam's age = Tia's age - 2
8 - 2 = 6
Veronica = pam's age + 5
6 + 5 = 11
Lily's age = veronica's age + 4
11 + 4 = 15
