An equation chain uses the solution of one equation to find the solution to the next equation in the chain. The last equation is then used to check your solutions. Complete each of the following equation chains.
1) 5 + a = 12, so a =
ab = 14, so b =
16 ÷ b = c, so c =
14 – d = c, so d =
e ÷ d = 3, so e =
a + e = 25  CHECK
