Question

plz solve this plz plz plz ​

Answer 1

Answer:

Step-by-step explanation:

a) 3(z-1)-2(4z-3)= 4z

  =3z-3-8z+6=4z

 = -5z+3=4z

= 3=4z+5z

=3/9=z

=z=1/3

b) (3/x+1)-(2/x-1)=5/x²-1

 = (3x-3/ x²-1) - (2x+2/x²-1) = 5/x²-1

= 3x-3-2x-2/x²-1 =5/x²-1

= (x-5/x²-1)*x²-1 = 5

= x-5 = 5

= x=10
