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

Answer:

#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"#
