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 y:( Make y the subject)

3x + y = 12

• y = 12 - 3x

• x = y + 4

• x = y + 12

• y = 3x -12
