Answer 3

if x = y
x- y = 0

4 * 0 = 0

7 = 7

your answer is 7 :)

Answer 4

Can you please go into more details on how you got that answer please ? but thank you

Answer 5

I don't know how to explain it but I can try >.<

so it gave you 'x=y' which means if you subtracted y from x, it'd be zero, since they're the same number, and you ALWAYs solve the parentheses first. (PEMDAS)

any number multiplied by 0 will be equal to 0

so 4(0) or 4* 0 or 4 x 0 will equal 0

then, all there is left is going to be;

0 + 7 = ?

the absolute value of |7|=?

is 7

therefore your answer would be 7 >.<
