Question

What number replaces the ◊?

15 = 15
15 + 4 + ◊ = 15 + 7

A. 3

B.4

C.19

D. 22

Answer 1

The answer is A.

15 + 4 + 3 = 15 + 7

Answer 2

A. 3

First, simplify the equation. (x means the same thing as the symbol)

19 + x = 22

Subtract 19 from both sides of the equation.

x = 22 - 19

x = 3

There’s the answer!
