• 8

• -8

• 3.2

• 4

Solve:
3(x - 2) = 18

• 6.7

• 4

• 8

• -4

Solve:
2(2x + 3) = -6(x + 9)

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

Solve for x. 
2x + 1 = 3x + 1 - x

• x = 0

• x = 1

• No Solution

• Infinite Solutions
