x=27/2

Explanation:

"isolate "(2x)/3" by adding 9 to both sides"

(2x)/3cancel(-9)cancel(+9)=0+9

rArr(2x)/3=9

"multiply both sides by 3"

cancel(3)^1xx(2x)/cancel(3)^1=3xx9

rArr2x=27

"divide both sides by 2"

(cancel(2) x)/cancel(2)=27/2

rArrx=27/2" is the solution"

x=13.5

Explanation:

(2x)/3 -9 =0

Take 9 to other side it will add to zero

(2x)/3=0+9

(2x)/3=9

Then,

2x=9*3

2x=27

x=27/2

x=13.5

x=13.5

Explanation:

First of all, you have to eliminate 9, so you add 9 on both sides. Now the equation is

(2x)/3=9

After that, you have to move 3 to the other side so you can solve for x, so you multiply by 3 on both sides. The equation becomes

2x=27

After that, you divide by 2 on both sides and

x= 13.5

To check your answer, replace 13.5 in for x in the original equation, which would be

(2(13.5))/3 - 9 = 0

x=27/2 = 13.5

Explanation:

(2x)/3-9 = 0

(2x)/3= 9

2x= 27

x= 27/2 = 13.5
