Hey!

Answer :

$x = \frac{c + 30}{6}$

where , x is age of Amy !!

Answer 2

Answer:

Amy's age = $\frac{1}{6} C+5$

Explanation:

• We know

                →  $(B - 5) = 3 (A - 5)$

                → $B - 5 = 3A - 15$

               → $B = 3A - 10$

• We also know

                → $(B-10)= 0.5(C-10)$

                → $2B - 20 = C - 10$

                →  $2B = C + 10$

• The questions asks for Amy’s age (a value for A) in terms of C :

                → $2 (3A - 10) = C + 10$

               → $6A - 20 = C + 10$

                → $6A = C + 30$

                → $A = \frac{1}{6} C + 5$
