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

8(m + 2)< 4(5 + 2m)

• no solution
• m < -2
• all real numbers
• m > 4

2 < 6z - 10 < 20

• -2 < z < -5
• z > 2 or z < 5
• 2 > z > 5
• 2 < z < 5

∣ m + 6 ∣ = 5

• m = -1
• m = -1 or m = -11
• m = 30
• m = 11

Solve
-5m < 10

• m < -2
• m > -2
• m < -50
• m > -50
