What is the value of x
-9x +12x = 45 - 36
3x = 9
x = 3/9 ~ simplify this
x = 1/3
Hope this helps

i get a different answer
(x x 5) - 9 = (x x 3) - 12 is the same as writing:
5x - 9 = 3x - 12
Then if u put x's on the left and numbers on the right:
5x - 3x = -12 + 9
2x = -3
x = -3/2
x = -1.5
Yew wa? I dont get it whats with the xxxx? Lmao

ok. :/
the first one is x as in the letter, and second is x as in multiplication
you can't multiply x by 5Originally Posted by Alex-S-89i get a different answer

If you check the answer I get:
(-1.5 x 5) - 9 = (-1.5 x 3) - 12
-7.5 - 9 = -4.5 - 12
-16.5 = -16.5

you might actually be right
I did this early in the morning and read the "minus 9" as a negative
i'm kind of old and haven't done this math in a little while lol
my work is acurate if they were negative numbers... otherwise
look at alex's work
sorry, I did in fact read it wrong

I think its this:Originally Posted by Existentialism-9x - 45 = -12x - 36
-9x +12x = 45 - 36
3x = 9
x = 3/9 ~ simplify this
x = 1/3
Hope this helps
-9x - 45 = -12x - 36
-9x +12x = 45 - 36
3x = 9
x = 9/3
x = 3 ..
That seems like the right answer to me Lol
