Answer:
18 and 12
Step-by-step explanation:
A - J = 6 ∴ J = (A - 6 )
A - 2J = - 6 (Subtitute J = (A -6) into the second equation gives Eq 3
(A - 2(A-6) = -6) = (A - 2A + 12 = - 6)
SIMPLIFY STEP 3 will give (-A = -18)
Age cannot be negative so multiply both sides by -1
This will give the grand answer of
A = 18
If Abigail is 18 now, 18 - 6 = 12
