Answer:

#w=6#

Explanation:

#"divide both sides by "3#

#cancel(3)/cancel(3)(2w+8)=60/3#

#rArr2w+8=20#

#"subtract 8 from both sides"#

#2wcancel(+8)cancel(-8)=20-8#

#rArr2w=12#

#"divide both sides by "2#

#(cancel(2) w)/cancel(2)=12/2#

#rArrw=6#

#color(blue)"As a check"#

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

#3(12+8)=3xx20=60=" right side"#

#rArrw=6" is the solution"#
