Question

I need help with 12 I don’t need a explanation I only need the answer I think i did something wrong in my work

Answer 1

Since Sahil got 28 questions right and Angelina got 7 more wrong answers, therefore Angelina's score is 7 lesser than Sahil. The equation will be 28 - 7 = Angelina's score. And based on the choices, it is a + 7 = 28.

Angelina's score is 21 and that is a.

So, if you substitute a with 21 to the second equation which is:

a + 7 = 28

21 + 7 = 28.
