-4 and 4
solution with [OH-] = 2.5 x 10-9 , A solution with [H+] = 1.2 x 10-4, A solution with pH = 4.5
0
4 equals numbers in a current account pin number
x=4 y=4

no.. x equals 11
No, it is not.
yes
4 equals numbers in a current account pin number
x = 0
y=x+4
(x, y) = (3, 7) is a solution.
x=4 y=4
No. -4 does not equal -2(1).
