Solving Linear Equations

8.ee.7a Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers).

Multiple Choice

Mariah solved the following equation but did not get the correct answer. What step did she do incorrectly?
Step 1:   -2(x - 4) - 6 = 12
Step 2:   -2x - 8 - 6 = 12 
Step 3:   -2x -14 = 12 
Step 4:   -2x = 26 
Step 5:      x = -13 

• Step 2 - she distributed incorrectly
• Step 3 - she combined like terms incorrectly
• Step 4 - she did not do the correct inverse operation
• Step 5 - she did not do the correct inverse operation 

WE DO!

​I DO!

• STEP 1: Identify the variable
