Question

. 3(5z - 7) - 2(9z - 11) = 4(8z - 13) - 17​

Answer 1

Answer:z=2

Step-by-step explanation:

3(5z-7)-2(9z-11)=4(8z-13)-17

Or, 15z-21-18z+22=32z-52-17

Or, -3z+1=32z-69

Or,35z=70

Or,z=70/35

Therefore z=2

Answer 2

Answer: z=2

Step-by-step explanation:

3(5z - 7) -2(9z-11) =4(8z-13)- 17

15z-21- 18z +22 =32z-52-17

-3z+1=32z-69

1+69=32z+3z

70=35z

2=z
