#x=3/2#

Solve: #1/7(7x-21)=8x+7x-24#

Simplify the right side.

#1/7(7x-21)=15x-24#

Multiply both sides by #7#.

#7x-21=105x-168#

Subtract #7x# from both sides.

#-21=105x-168-7x#

Simplify.

#-21=98x-168#

Add #168# to both sides.

#168-21=98x#

Simplify.

#147=98x#

Divide both sides by #98#

#147/98=x#

Simplify.

#3/2=x#

Switch sides.

#x=3/2#
