Don't worry....it's not a homework question. It's a practice question for a test. But, here's the equation: 2/3x= -8.
How do I get the answer for this. I got -16/3, but I'm sure that's not correct haha.
thnx=]

I'm not sure which problem you asking. Is it 2 divided by 3x equals -8; or is it 2/3 times X = -8. Anyway, I'll work them both.
2 divided by 3x equals -8
2/3x = -8
Cross multiply so lets give -8 a denominator of 1
2/3x = -8/1
-24x = 2
Now divide each side by -24 so you are left with x
-24x/-24 = 2/-24
x = 2/-24 = - 1/12 answer is negative 1/12
Or is it 2/3 times X equals -8
2/3x = -8
A positive times a negative is equal to a negative, so we know that X is negative.
Lets divive 2/3 by each side so we are left with x and we get
x = -8 divided by 2/3
To get x we must multiply and change the 2/3 to 3/2
x = -8/1 * 3/2
x= -24/2 = -12 answer is -12

Here, times:
(3/2) 2/3x= -8 (3/2)
x= -8(3/2)
x= -4(3)
x=12

2/3x=-8
divide 2/3
x=negative 12

2/(3x) = -8.
Multiply both sides by 3x,
2 = -24x
x = -1/12

2/3x=8
multiply both sides by 3
2x=24
x=12

Assume question is meant to be:-
(2/3) x = - 8
2x = - 24
x = - 12
PS
Take care with brackets â¥!!!
