Here is the equation
(3x + 5)(2x 3) = (x 1)(6x + 5)
the supposbly answer is x = 5, is the answer true or false? Please can anyone help here, I think its false, but I need to be sure I'm right. ^^

sorry about that its " - "
(3x + 5)(2x 3) = (x - 1)(6x + 5)

If you meant (3x + 5)(2x - 3) = (x - 1)(6x + 5) (see the added subtract signs) then the answer is indeed x = 5.

The answer is x=5, and the equation should read (3x+5)(2x-3)=(x-1)(6x+5). When you plug 5 in for x you get 140=140. So there for it is true.

I'm assuming the blanks are negatives
(3x + 5)(2x - 3) = (x - 1)(6x + 5)
6x^2-9x+10x-15 = 6x^2 + 5x -6x -5
6x^2 + x - 15 = 6x^2 - x - 5
2x = 10
x = 5
So true.

this says:
(3*5 + 5)(2*5-3)=(5-1)(6*5 +5)
(15+5)(10-3)=(4)(30+5)
20*7=4*35
140=140
now tell me the answer!!!!
all you do is replace the value of x and do the math....

False, if you wrote the problem out right, it looks like you missed some symbols... But if everything is typed out right 450 does not equal 150.
Oh ok, if those are "-" than the answer is True.

What are these? (2x 3) and (x 1)? Are you missing operators, or are these supposed to be exponents?

It's going to be impossible to answer this if you don't type it in more carefully. Is that second x supposed to be the variable or multiplication?
