Presentation transcript:

Bell work Build the following expressions to find which is greater: x + 1 − (1 − 2x) or 3 + x − 1 − (x − 4)

Today you will explore more equations on the Equation Mat and will examine all of the tools you have developed so far to solve for x. While you are working on these problems, be prepared to answer the questions that follow. How can you simplify? Can you get the variable alone? Is there more than one way to simplify? Is there always a solution?

2-81. On your paper, write the equation represented in each diagram below. For each equation, simplify as much as possible and then solve for x or y. Be sure to record your work on your paper. a. b.

2-82. IS THERE A SOLUTION? While solving homework last night, Richie came across three homework questions that he thinks have no solution. Build each equation below and determine if it has a solution for x. If it has a solution, find it. If it does not have a solution, explain why not. Explore using the virtual tiles below. a. 2-82a tiles b. 2-82b tiles c. 2-82c tiles
