it's the same thing

-4x=12/13

-52x=12

-x=12/52

x=-12/52

x= - 3/13

or you could go

-4x=12/13

x=(12/13)*(-1/4)= - 3/13

-_-....

first do 12 / 13 on a calculator

then, divide by -4 the number you get.....

note: don't divide by zero.

edit: 12/13 = fraction yes... a fraction is a division.

1/2 = 0.5

0.5 is the half of 1 no?

2/2 = 1

if you really do want a fraction though, just put the number you get when you divide by -4 on 1.

well i don't have a calculator so im jsut gonna show the work you can do the rest.

-4x=12/13

(-1/4)(-4)=(12/13)(-1/4)

x=(12/13)(-1/4)

just do the math and there you have it. lol........

-4x=12/13
x= -(12/13) * (1/4) divide the -4 on other side (in this case multiply by - 1/4)
x= -(12/(13*4)) can multiply factors (times the top and the bottom
x= -(3/13) The 12 is reduced to 3 from dividing 12 by 4

there you go, hope this lines up right on page
