3X = 9
divide both sides integers by 3
(3/3)X = 9/3
X = 3
-------------check in original equation, put 3 in for X
3(3) = 9
9 = 9
----------checks
x=9 is as simple as it gets. The question is the solution.
The solution is k = 9.
y= -9
9
That's an invalid equation.
(x, y) = (3, 7) is a solution.
solution with [OH-] = 2.5 x 10-9 , A solution with [H+] = 1.2 x 10-4, A solution with pH = 4.5
5.6
I don't believe it is a solution.
9 plus 7 equals 16.
D - 9 = 9 d = 9 + 9 d = 18
x = -6
