Question

PLEASE HELPPP MEEE OUTTTTTT

Answer 1

3. b= 5

4. d= -5

5. z= 2/3

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

Answer 2

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
