Even though you might be totally convinced that what you have given in the question
is completely meaningless, there is actually a load of information there.
I can see six equations in the question. They are:
1). a = 20 m2 b
2). a = h
3). a = 4
4). 20 m2 b = h
5). 20 m2 b = 4
6). h = 4
Since there are four variables involved ... a, m, b, and h ... there must be four 'answers'.
Equations #2, #3, and #6 tell us that 'a' and 'h' are both equal to ' 4 '.
That leaves us three more equations to find 'm' and 'b'.
Unfortunately, Equations #1, #4, and #5 are now all the same equation . . .
[ 20 m2 b = 4 ], or [ m2 b = 0.2 ].
Without two independent equations, there's no way to find 'm' and 'b'.
I'm sorry to have taken you through this long, boring discussion. What you really
need to do is to go way back to the beginning ... even before you posted your
question ... and before you ask for answers, take a little more time to make sure
you have an idea of what the question is, and maybe even what the answer is
going to look like. That way, you may be able to spot the answer when it comes
along.
h - 4 = 10 Therefore, h = 10 + 4 h = 14

3+h/6 7-3(h/6) 4(h/6) 4*6=24 24/6=4 4+3=7 Therefore the variable h equals 24
solution with [OH-] = 2.5 x 10-9 , A solution with [H+] = 1.2 x 10-4, A solution with pH = 4.5
4h = 36 Therefore h = 36/4 h = 9
4 equals H a h s o w a w? WHAT IS THE ANSWER
h - 4 = 10 Therefore, h = 10 + 4 h = 14
(1,6) and (4, -3).
