Answer 1

The answers are x = 18 x = -12 x = 2.4

Explanation:

In the first question you multiply 12 by 2/3 and get x = 18

In the second one you then multiply both sides of the equation by 5/6 and get x = -12

In the third equation you divide 12 by and and you get x = 2.4

Answer 2

18. x=18

since you would eluminate the fraction you would have left x=12*3/2

12*3/2=18

so x=18

19.

x=-12

Once you subtract 2 two from both 2 and the -8 you would have x=10*-6/5

10*-6/5=-12

The answer is -12

20.

x=2.4

you would divide both numbers by 5 and 12/5=2.4

so the answer is x=2.4
