Question

solve and verify by LHS and RHS 2z/3 —5=3z/4—1

Answer 1

2z/3-5=3z/4-1
2z/3-3z/4=-1+5
-z/12=4
-z=4*12
z=-48

Answer 2

(2 z/3) - 5 = (3 z/4) -1

taking l c m of both sides

(2z - 15)/ 3 = ( 3z - 4) / 4

by cross multiplication

8z - 60 = 9z - 12

8z - 9 z = -12 + 60

  - z  = 48 so

z = - 48
