Question

What's the answer to this question because I'm really confuse and could u explain how u got it.

Answer 1

take the blank as an x

Explanation:

14 - x = 2³ + 5

x = 2³ - 9

x = -1

Answer 2

Hey there!

14 - ? = 2^3 + 5

14 - x = 2^3 + 5

14 - x = 2 * 2 * 2 + 5

14 - x = 4 * 2 + 5

14 - x = 8 + 5

14 - x = 13

-x + 14 = 13

SUBTRACT 14 to BOTH SIDES

-x + 14 - 14 = 13 - 14

SIMPLIFY IT!
-x = 13 - 14

-x = -1

-1x = -1

DIVIDE -1 to BOTH SIDES

-1x/-1 = -1/-1

SIMPLIFY IT!
x = -1/-1

x = 1

Therefore, your mystery number should be: 1

Good luck on your assignment & enjoy your day!
