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.

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"#
