Answer:

#x=2#

Explanation:

Apply the distributive property

#2x+2*7+x=20#

Multiply by #7# to get #14#

#2x+14+x=20#

Add #2x# and #x# to get #3x#

#3x+14=20#

Since #14# does not contain the variable to solve for, move it to the right side of the equation by subtracting #14# from both sides.

#3x=-14+20#

Add #-14+20# to get #6#

#3x=6#

Divide each term by #3# and simplify.

Answer : #x=2#
