Which ordered pair will solve the equation 2 × 4 + x = y?
Bezzdna [24]
This answer uses NMF, which you can find out about on my profile:

Preliminary work:
Following the BIDMAS order of operations, we can calculate part of it already, and that's the 2•4, which equals 8.
Therefore, the equation now reads:
8+x = y

x = 5:
8+5 = 13
13 ≠ 16
13 ≠ y

x = 4:
8+4 = 12
12 = 12
12 = y

Therefore, the pair is (4, 12)

I don’t understand!!!!!

These are vertical angles, meaning they're always the same length.

3x = x + 28

2x = 28

x = 14
