12

Explanation:

To start out, you multiply 3 to both sides to get rid of the denominator on the right.

After doin this you get 24 = 2d, next divide by two and ya getcha answer to be d=12.

d=12

Explanation:

"note that "2/3d=(2d)/3

"to eliminate the fraction multiply both sides by 3"

3xx8=cancel(3)xx(2d)/cancel(3)

rArr24=2d

"divide both sudes by 2"

24/2=(cancel(2) d)/cancel(2)

rArr12=d" or "d=12

color(blue)"As a check"

Substitute this value into the right side of the equation and if equal to the left side then it is the solution.

"right "=2/cancel(3)^1xxcancel(12)^4=2xx4=8="left"

rArrd=12" is the solution"
