find the value of the variable that would make the equation true..

1.) 5x = 15
2.) -3x = 21
3.) 9x = -27
4.) -7x = -12
5.) 2/3 x = 8

you want to get x by itself, so divide by its coefficient:

#2:
-3x = 21
divide both sides by -3 and you have
x = -7

#5:
divide by 2/3 -- that's the same as multiplying by 3/2, so

x = 8 * 3/2 = 12

Now you can probably do the others, no?
3) -3

bkt
Honestly,I dont have an answer butttttt,what value of 3x makes this question true?
