Answer

z= 14

Step-by-step explanation:

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

8z-12-5z+30=60

3z+18=60

3z=60-18

3z=42

z= 14

[tex] \frac{2z - 3}{5} - \frac{z - 6}{4} = 3 \\ = > \frac{4(2z - 3) - 5(z - 6)}{20} = 3 \\ = > \frac{8z - 12 - 5z + 30}{20} = 3 \\ = > \frac{3z + 18}{20} = 3 \\ = > 3z + 18 = 3 \times 20 \\ = > 3z + 18 = 60 \\ = > 3z = 60 - 18 \\ = > 3z = 42 \\ = > z = \frac{42}{3} \\ = > z = 14[/tex]

Answer:

z = 14
