• check the solution.
• guess and check.
• Combine Like Terms.

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

• x = 12
• no solution
• x = 10
• x = 6

Which of the equations has no solution?

• 2x + 1 = 5x - 3
• 2(x - 7) = 2x-14
• 3(2x+1) = 6x+1
• 15x - 30 = 0

What is the solution to this equation?

• one solution
• no solution
• infinite solutions
• none of these
