Are you solving this problem if yes then try to bring the x variables to the left side so your first problem
9/2 x-3/4=7/2 x+5/4
7/2x would be brought over and subtracted form 9/2x which would equal 16/2x. <----I don't think so!!!Then the sums to the right side so 3/4 added to 5/4 which equals 8/4. "Remerber that signs change when pasted over.
so your problem now is
19/2x = 8/4
Now how would you divde 8/4 by 19/2 and there is what x equals easy to do with scientific calualator.
If your first problem is (9/2)x - 3/4 = (7/2)x + 5/4, then your first step might be to subtract (7/2)x from both sides so that you eliminate the "x" term from one side:
(9/2)x - (3/4) - (7/2)x = (7/2)x + (5/4) - (7/2)x
You can combine like terms. (9/2)x - (7/2)x is (2/2)x, or just x, and you'll then have
x - (3/4) = (5/4)
Now...can you finish?
Be sure to check your answer...whatever value you get for x should make the original equation true.
