Respuesta :

B=5 this is because you need to isolate the b so you first add 3 to both sides and then it’s going to be 5b=25 and then divide 5 from both side to get b by itself and it will be b=5

Answer:

3. b= 5

4. d= -5

5. z= 2/3

Step-by-step explanation:

3) 5b-3=22

   5b=25     add 3 to both sides

   b= 5        divide 5 from both sides

4) 1.5d+3=-4.5

   1.5d=-7.5    subtract 3 from both sides

   d=-5           divide 1.5 from both sides

5) 4=9z-2

   6=9z       add 2 to both sides

   6/9=z      divide 9 from both sides

   2/3=z      simplify
