#### Storyboard Text

• Hello class! Today we will learning about algabretic expressions!
• 1/2x + 8 = 22
• In order to find the solution we need to isolate the variable. So we first need to get rid of the 8 and to do that we need to use the inverse operation as shown on the board.
• 1/2x + 8 = 22
• - 8
• - 8
• Now we solve!
• 1/2x + 8 = 22
• 1/2x =
• - 8
• - 8
• 14
• Now we have to isolate the variable one last time. so to do this we have to multiply by the reciprocal to get rid of the 1/2. As shown on the board.
• 2/1 • 1/2x
• 1/2x + 8 = 22
• 1/2x =
• - 8
• - 8
• 2/1 • 14
• 14
• Now we solve!
• 2/1 • 1/2x
• 1/2x + 8 = 22
• 1/2x =
• - 8
• x =
• 2/1 • 14
• 28
• - 8
• 14
• Good job!
• + 8 = 22
• - 8
• - 8
