Question

Plz help me if you're nice. If wrong answer i'll report you

Answer 1

z= 14

Explanation:

4( 2z-3) -5(z-6) =3 *20

8z-12-5z+30=60

3z+18=60

3z=60-18

3z=42

z= 14

Answer 2

`(2z - 3)/(5) - (z - 6)/(4) = 3 \\ = > (4(2z - 3) - 5(z - 6))/(20) = 3 \\ = > (8z - 12 - 5z + 30)/(20) = 3 \\ = > (3z + 18)/(20) = 3 \\ = > 3z + 18 = 3 * 20 \\ = > 3z + 18 = 60 \\ = > 3z = 60 - 18 \\ = > 3z = 42 \\ = > z = (42)/(3) \\ = > z = 14`

Answer:

z = 14

Hope you could get an idea from here.
