Question

Simplify and solve: 3(5z-7)-2(9z-11)=4(8z-13)-17

Answer 1

Answer:

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

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

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

-3z+1=32z-69

-3z-32z=-69-1

-35z=-70

z=-70/-35

z=14/7

z=2 (Ans)

Answer 2

Answer:

after multiplying we get the value

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

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

-35z= -70

cancelling minus , we get

35z=70

z=35/70

z=2

so after simplifying we get the value of z=2
