Question

how to simplify a+6d=24 and a+16d=54​

Answer 1

Answer:

a = 6 , d = 3

Step-by-step explanation:

a = 24 - 6d ----> (1)

a = 54 - 16d ----> (2)

Since, LHS of both (1) & (2) is equal, it can be equated.

24 - 6d = 54 - 16d

16d - 6d = 54 - 24

10d = 30

d = 3

Put value of 'd' in (1) or (2).

a = 24 - 6(3) = 24 - 18 = 6

a = 6
