Solve the equation:
3(x - 1) = 2x + 9

• x = 12
• no solution
• x = 10
• infinite solutions

Solve the equation:
3x - x + 2 = 0.5(4x - 8)

• infinite solutions
• x = 1
• x = -1
• no solution

Work out the value of the expression when a = 5, b = -1 and c = 2.

• 2

• -2

• 4
• -4

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
