Using substitution which number from the set [8,12,16,20] makes the equation x/4 +2=5 true

Answer 1

Let's substitute each number into the equation and see which one makes it true:

1. When x = 8:
8/4 + 2 = 2 + 2 = 4 ≠ 5

2. When x = 12:
12/4 + 2 = 3 + 2 = 5

3. When x = 16:
16/4 + 2 = 4 + 2 = 6 ≠ 5

4. When x = 20:
20/4 + 2 = 5 + 2 = 7 ≠ 5

Therefore, the only number from the set [8, 12, 16, 20] that makes the equation true is 12.
