Question

find the value of z : (z/6) -( 2z/3) = 7​

Answer 1

z/6-2z/3 = 7

z-4z/6 = 7

-3z/6 = 7

-3z = 7x6

-3z = 42

z= 42/-3

z= -14

Answer 2

Step-by-step explanation:

we have to solve the question ,z

/2+z/3-z/6 =8

Taking. LCM of denominatora of (z/2), (z/3) and (z/6)

or ,LCM of( 2,3,6)=6

now now write each fraction in such a way that determinator to it will be 6

I.e..,z/ 2 =( 3xz) /( 3x2) =3z/6

z/3=(2xz)/(2x3)=2x/6

z/6=(1xz)/(1x6) =z/6

now , z/2+z/3-z/6 is converted into (3z/6+/6+2z/6-z/6=8

so, 3z/6+2z/6-z/6=8

or , (3z+2z-z)/6 =8

or,(5z-5)/6=8

or , 4z/6=8

or z=12

hence , value of z =12
