Question

2.25 (2z + 8)=5z -3​

Answer 1

Answer:

     z = 42

Step-by-step explanation:

2.25 ( 2Z + 8 ) = 5z - 3

4.5z + 18 = 5z - 3

5z - 4.5z = 18 + 3

       0.5z = 21

            z = 21/0.5

            z = 21 x 10/5

            z = 42

 

Answer 2

Answer:

4.5z+18=5z-3

5z-4.5z=18+3

0.5z=21

z=21/0.5

z=21×10/5

z=42
