Question

Mila and Ava play a number game. Mila gives Ava a number and she does three computations:

She subtracts 5 from that answer.
She multiplies the number by 2.
Then, she adds 8 to the answer.
What number should Mila give Ava so that the final answer is 92?

Answer 1

Explanation:

2(n-5)+8=92

2n-10+8=92

2n-2=92

2n=94

n=47

Answer 2

Explanation:

(x-5)2+8 = 92

2x-10+8 = 92

2x = 94

x = 47
