Treat the larger than or equal sign as an equals sign.

#-5x = 7(x+7)-13 #

Expand the bracket

#-5x = 7x+49-13#

Simplify

#-5x = 7x+36#

Minus the #36# and add the #5x#, you want the #x# to be positive

#-36 = 12x#

Divide by #12# on both sides

#-3 = x#

Replace equals with larger than or equals sign

#-3 >= x#
