really easy math problem... but i forgot how to do it!? help?

Question

a = -3
--- ------
-6 2

i wanna make this inti a= ______ form

really easy, right? but i forgot how to do it... somewhere in my mind...

whoa that look so hard to understand....

here:
a/-6 = -3/2

Answer 1

cross multiply
a/-6 = -3/2
18 = 2a
a = 9

Answer 2

Here is the answer with an in-depth explanation.


Step one: cross multiply a X 2= 2a and -6 X -3= 18
** Remember a negative number times a negative number equals a postive number; that is why -6 multiplied by -3 equals +18

After step one the equation now looks like: 2a=18


Step two: divide both sides of the equation by 2 (2a/2=a and 18/2=9)
**To solve the problem we must get "a" on one side of the equal sign by itself. To do this we must reverse the operation (do the opposite of what was done in the equation); the opposite of multiplying "a" by 2 is dividing "a" by 2. In alegebra, what you do on one side of the equal sign, you must do on the other side of the equal sign; so now you have to divide 18 by 2.

Final anwer: a=9

Answer 3

a=9

Answer 4

well u have 2 cross multiply so ul have um 2a = 18 then divide both sides by 2 and u will get a=9

Answer 5

a/-6 = -3/2
a = -3/2 * -6 (Multiply both sides by -6)
a = (-3*-6)/2
a = 18/2
a = 9

Answer 6

cross multiply
2a = 18
divide by 2 on both sides
a = 9

Answer 7

cross multiply

2a = (-3)(-6) = 18

2a = 18

a = 9

Answer 8

multiply by -6
a=(-6)(-3/2)=9

Answer 9

Yeah all the answers are correct

good luck

Answer 10

a=-3/2x-6
