Solve Equations Increasing Difficulty

Solve for x:
5 + 3x = 8x - 15

• 10
• 4
• 2
• 20/11

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
