Question

Max is thinking of a number, which he calls n. He adds 8 and then doubles the sum. What is Max's final number if his starting number is 7? i need help pls

Answer 1

Based on the given situation, Max final number if his starting number is 7 is -4.5

Algebra

• Unknown number = n

• He adds 8

n + 8

• then doubles the sum

2(n + 8)

• starting number = 7

So,

2(n + 8) = 7

2n + 16 = 7

2b = 7 - 16

2n = -9

n = -9/2

n = -4.5
