Question

3(5z-7)-2(9z-11)=4(8z-13)-17​

Answer 1

Answer:

Step-by-step explanation:

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

After opening the brackets

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

-3z+1=32z-69

By shifting -69 to L.H.S and -3z to R.H.S

1+69=32z+3z

70=35z

z=70÷35

z=2

Hope it help!!

Answer 2

Answer:

step wise I will answer

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

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

=>15z-18z-32z=-69+21-22

=>15z-50z=-91+21

=>-35z=-70(minus and minus will cut out)

=>35z=70

=>z=70÷35

=>z=2

Therefore, z=2 (Answer)
