That's an invalid equation.
solution with [OH-] = 2.5 x 10-9 , A solution with [H+] = 1.2 x 10-4, A solution with pH = 4.5
4x+9=25 4x=16 x=4
y= -9

Since 'x' appears only to the 1st power, this is a linear equation,and there's only one solution.4x + 9 = 25Subtract 9 from each side:4x = 16Divide each side by 4:x = 4

(x, y) = (3, 7) is a solution.
yes it is..your welcome
yes
4x+9=25 4x=16 x=4
x=9 is as simple as it gets. The question is the solution.
The solution is k = 9.
y= -9
4 times 9 equals thirty six. Thus, 36 divided by 4 equals nine.
