OKAY
3X / 7 = -3
(3X / 7) (7) = (-3) (7)
3X = -21
3X / 3 = -21 / 3
x = -7
Check:
-21 / 7 = -3 Correct -3 = -3

3x/7= -3
if you are looking for the value of x
multiply by 7 in both sides
3x = -21
then divide by 3
x = -7

your going to divide the 7 out becuase the opposite of division is multiplication so
(3x/7)*7 =-3*7
becuase what you do to once side you have to do to the other. so
3x =-21
and then divide 3 out and once again do it to the other side therefore
x= -7
