How to solve the 7 x + 3 = 13 + 2 x type of equation

How to solve the 7 x + 3 = 13 + 2 x type of equation. The 7, 3, 13 and 2 could be any numbers. 7x + 3 = 13 + 2x 7x + 3 – 3 = 13 + 2x - 3. You get rid of the + 3 with a - 3. 7x + 3 = 13 + 2x 7x + 3 – 3 = 13 + 2x - 3 7x = 10 + 2x. You get rid of the + 3 with a - 3.

  1. How to solve the7x + 3 = 13 + 2xtype of equation The7, 3, 13and2 could be any numbers

  2. 7x + 3 = 13 + 2x 7x + 3 – 3 = 13 + 2x - 3 You get rid of the + 3with a - 3

  3. 7x + 3 = 13 + 2x 7x + 3 – 3 = 13 + 2x - 3 7x = 10 + 2x You get rid of the + 3with a - 3

  4. 7x + 3 = 13 + 2x 7x + 3 – 3 = 13 + 2x - 3 7x = 10 + 2x 7x – 2x = 10 + 2x – 2x You get rid of the + 3with a - 3 Get rid of the 2x by taking away 2x from both sides

  5. You get rid of the + 3with a - 3 7x + 3 = 13 + 2x 7x + 3 – 3 = 13 + 2x - 3 7x = 10 + 2x 7x – 2x = 10 + 2x – 2x 5x = 10 Get rid of the 2x by taking away 2x from both sides then divide both sides by 5

  6. 7x + 3 = 13 + 2x 7x + 3 – 3 = 13 + 2x - 3 7x = 10 + 2x 7x – 2x = 10 + 2x – 2x 5x = 10 x = 10/5 You get rid of the + 3with a - 3 Get rid of the 2x by taking away 2x from both sides then divide both sides by 5 Divide both sides by 5

  7. 7x + 3 = 13 + 2x 7x + 3 – 3 = 13 + 2x - 3 7x = 10 + 2x 7x – 2x = 10 + 2x – 2x 5x = 10 x = 10/5 x = 2 You get rid of the + 3with a - 3 Get rid of the 2x by taking away 2x from both sides then divide both sides by 5 Divide both sides by 5

  8. 5x – 3 = 21 – x Here is another example The 5, 3 and 21 can be any numbers

  9. 5x – 3 = 21 - x You get rid of the – 3by + 3

  10. 5x – 3 = 21 - x 5x – 3 + 3 = 21 + 3 You get rid of the – 3by + 3

  11. 5x – 3 = 21 - x 5x – 3 + 3 = 21 + 3 5x = 24 – x You get rid of the – 3by + 3

  12. 5x – 3 = 21 - x 5x – 3 + 3 = 21 + 3 5x = 24 – x You get rid of the – 3by + 3 Get rid of the - x by a + x on both sides

  13. 5x – 3 = 21 - x 5x – 3 + 3 = 21 + 3 5x = 24 – x 5x + x = 24 – x + x You get rid of the – 3by + 3 Get rid of the - x by a + x on both sides

  14. 5x – 3 = 21 - x 5x – 3 + 3 = 21 + 3 5x = 24 – x 5x + x = 24 – x + x 6x = 24 You get rid of the – 3by + 3 Get rid of the - x by a + x on both sides

  15. 5x – 3 = 21 - x 5x – 3 + 3 = 21 + 3 5x = 24 – x 5x + x = 24 – x + x 6x = 24 x = 24/6 You get rid of the – 3by + 3 Get rid of the - x by a + x on both sides Divide both sides by 6

  16. 5x – 3 = 21 - x 5x – 3 + 3 = 21 + 3 5x = 24 – x 5x + x = 24 – x + x 6x = 24 x = 24/6 x = 4 You get rid of the – 3by + 3 Get rid of the - x by a + x on both sides Divide both sides by 6

  17. Try these

  18. Remember, always do the same thing to both sides. Felix is checking that you do this properly. 5x + 3 = 43 + 3x 5x + 3 – 3 = 43 – 3 5x = 40 + 3x 5x – 3x = 40 + 3x – 3x 2x = 40 x = 20
