Find the solution to the following problem:

x+2=x+4

• all real numbers

• x=0

• no solution

• many solutions

CCSS.8.EE.C.7A

Solve for x:

-6(2v + 4) = -8(v - 4)

• -8

• -13

• -14

• 14

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k
