1. Given

2. Substitution Property

3. Addition Property of Equality

4. Division Property of Equality

5. Symmetric Property of Equality

• 1. 3y=5x-39 and y=7

  2. 3y= 5(7)-39

  3. 3y = 35-39

  4. 3y = -4

  5. y=-4/3

• 1. 3y=5x-39 and y=7

  2. 21= 5x-39

  3. 60 = 5x

  4. 12 =x

  5. x=12

• 1. 3y=5x-39 and y=7

  2. 3(7)= 5x-39

  3. 21 = 5x-39

  4. 60 =5x

  5. 12=x

• 1. 3y=5x-39 and y=7

  2. 3(7)= 5(12)-39

  3. 21= 60-39

  4. 21 =21

  5. x=12
