1. Solving Systems of Equations using Substitution By: Kashae Alexander 2. Step One:

  • y = 3x+ 29 3. y = 7x + 5

4. Step Two:

  • y = 3x+ 29 y = 7x + 5
  • y = 3x+ 29=7x + 5

5. Step Three

  • 3x+ 29=7x + 5 -3x-3x 29=4x+5

6. Step Four

  • 29=4x+5 -5-5 24=4x

7. Step Five: Finding The X

  • 24=4x 24/4
  • X=6

8. Step 6: Finding Y

  • y = 3x+ 29y = 7x + 5 9. Y=3(6)+29y= 7(6)+ 5 10. Y=47y=47

11. Solution

  • (6,47)
