• ﻿﻿﻿﻿First you simplify the equation and add +2x to both sides of the equation
• ﻿-3(2x+5)=15
• Jake, would you solve this equation for the class﻿ ?
• ﻿
• ﻿3(x+4)=-2x-18
• Chase, What is the first ﻿step to solving this equation ?
• Yes
• ﻿-3(2x+5)=15
• 3﻿
• ﻿-6x +-15=15
• ﻿﻿﻿﻿﻿﻿﻿-6
• _﻿__﻿
• ﻿
• x=-5﻿
• ﻿﻿﻿﻿﻿﻿﻿-6
• _﻿__﻿
• +15﻿
• 3﻿
• ﻿
• -6x=30﻿
• +15﻿
• First you subtract -3 from both sides﻿ of the equation, then add 15 to both sides
• ﻿-3(2x+5)=15
• 3﻿
• ﻿﻿﻿﻿﻿﻿﻿-6
• ﻿-6x +-15=15
• _﻿__﻿
• _﻿__﻿
• ﻿﻿﻿﻿﻿﻿﻿-6
• +15﻿
• -6x=30﻿
• 3﻿
• +15﻿
• x = -5﻿
• ﻿﻿+2x﻿
• 3x+12=-2x-18﻿
• ﻿﻿+2x﻿
• Then you subtract 12 from both sides of the equation ﻿
• ﻿﻿
• ﻿-12﻿
• 5x+12=-18
• 5x=-30
• -12
• To get your answer you divide 5 to get rid of 5 and whatever you do to one side you do to the other
• ﻿
• ﻿﻿5﻿
• ﻿﻿____﻿
• ﻿﻿x=-6﻿
• 5x=-30
• ﻿﻿____﻿
• ﻿﻿5﻿
