Storyboard Text

  • Solve this Equation                                                            2(4x-3)-8= 4 + 2x    8x - 6 - 8= 4 + 2x                                                                          
  • Students, this is how you solve the problem. 2 times 4x is 8x. Then, 2 times -3 is -6. After these, you copy the rest of the problem. 
  • 
  • 
  • Then, you -6 is subtracted from -8 which is -14. Then, you combine like terms from both sides, when -14 moves to the right side and 2x moves tothe left side. When combining like terms, you have to change from positive to negative or vice versa.
  • 8x - 14 = 4 + 2x 8x - 2x = 4 + 14
  • On this part of the problem, 8x is subtracted to 2x which is 6x. In the other side, 4 is added to 14 which is 18. Because you have to isolate the variables, you have to move the 6 to the other side, so 18 divided by 6 is 3. The final answer is x equal to 3. 
  • 8x - 2x = 4 + 14  6x = 18 x = 18       6 x = 3
