Question

Equation A: 3 + 5 = 8

Equation B: (3 + 5) / __ = 4
Choose the number that will make equation A equivalent to equation B.

Answer 1

The answer is 2.

Explanation:

Remeber to always use PEMDAS.

1. (3 + 5) / x = 4 - We do the addition in the parenthesis first.

2. 8 / x = 4 - We now want to find what x means, to do this we divide the answers by the number we already have.

3. 8 / 4 = 2 - Now we can do the initial equation with the number we found to test it.

4. 8 / 2 = 4 - Simple as that :)

Answer 2

2

Explanation:

(3+5)/2=4

8/2=4

which is true
