#### Storyboard Text

• ﻿Explain how to solve the equation on the board.
• -2 (3/4c+9) = 1/4 (8-c)﻿
• -1.5c-18 = 2-1/4c
• First I distributed the -2 and the 1/4 to the parentheses on the correct side.﻿
• I'm confused.﻿
• ﻿17.5c=-2c
• ﻿Once you have distributed, you combine the numbers on each side of the equal sign
• ﻿I thought you had to combine like terms
• Does anyone agree with Matthew?﻿
• 17.5c=-2c﻿
• I thought you were supposed to combine like terms﻿
• Would you like to show us Cathy?﻿
• -2(3/4c+9)=1/4(8-x) -3/4c-18=2-1/4c -6c-72=8-x -6x+x=8+72 -5c=80 divide both sides by 5 c=-16
• ﻿wow. I didn't know that not combining like terms would mess up my problem so much
• ﻿That's what I got too
• ﻿Great job kids
• verify: -2[3/4(-16)+9]=1/4(8+16) -2(-12+9)=1/4(24) -2(-3)=1/4(24) 6=6
• I understand now!﻿
