Distribute, combine like terms, and solve for x

Explanation:

#7(3x + 7)\le7 + 6(6x -3)#

Distribute the 7 through the first set of parenthesis, and the 6 through the second set of parenthesis

#21x +49\le7 +36x - 18#

Combine like terms on the right side of the equation

#21x + 49\le36x -11#

Subtract 49 from both sides of the equation

#21x\le 36x - 60#

Subract 36x from both sides of the equation

#-15x\le -60#

Divide both sides of the equation by -15, and flip the inequality symbol because you're dividing by a negative

#x\ge 4#
