  1. What happens if we solve an equation and the answer doesn’t look right? X + 4 = X + 3 -X =-X 4 = 3

  2. In this lesson you will learn that a linear equation has no solutions by transforming it into a simpler form.

  3. = 5 X + 2

  4. X + 2 = 5 -2 -2 X = 3

  5. = 3 X

  6. = 5 X + 2

  7. X+ 2 = 5 X+ 2 = 5 4 + 2 = 5 3 + 2 = 5 5 = 5 6= 5  

  8. = 5 X + 2

  9. Thinking that your math is wrong if both sides of the equation are not equal

  10. What is the solution of x+1=x? X + 1 = X -X = -X 1 = 0  No Solution

  11. How many solutions does this equation have? 2x + 7 + 5x = 7(x+8) 7x + 7 = 7x + 56 -7x = -7x  7 = 56 No Solution

  12. 7x + 7 = 7x + 56 X + 1 = X

  13. x + 1 = x

  14. 0 = 1

  15. In this lesson you learned that a linear equation has no solutions by transforming it into a simpler form.

  16. How many solutions does 2x–2 = 2x have?

  17. Is 5 a solution for y-1=y?

  18. When we solve the equation x+5=x+2, what is our solution? What does this mean?

  19. How many solutions does the equation x+3x+4 = 4x have? Why?

  20. What can you tell about the structure of an equation that has no solution?

  21. What is the solution for the equation 9x-x = 3(3x-2)? a) -10 b) 0 c) -2 d) no solution What is the solution for the equation x-1 = x+2? a) -3 b) 0 c) 3 d) no solution
