Step-by-step explanation:
b+t+s=37
b=t+6
s=t-8

t+6+t+t-8=37
3t-2=37
+2 +2
3t=39
divide by 3
t=13
plug in
b=13+6=19
s=13-8=5
t=13, b=19, s=5

Answer:
Tanya is 13 years old
Brandon is 19 years old
Sam is 5 years old
Step-by-step explanation:
Tanya is (x) 13
Brandon is (x+6) (13)+6=19
Sam is (x-8) (13)-8=5
(x)+(x+6)+(x-8)=37
combine like terms
3x-2=37
add 2 to both sides
3x-2=37
+2 +2
3x=39
divide 39 by 3
3x=39
÷3 ÷3
x=13
