=  > 3x - 4y + z + 1 - 2x + y

= 3x - 2x - 4y + y + z + 1

\bold{= x  - 3y + z + 1.......(1)}

=  > 3y + z + 6 + x - 2y + 3

= x + 3y - 2y + z + 9

\bold{= x + y + z + 9.......(2)}

Now,subtracting equation (1) from equation (2)

=  > x + y + z + 9 - (x - 3y + z + 1)

= x + y + z + 9 - x + 3y - z - 1

=>Here,when we open BRACKET -x and -z will come which will being cancelled by EXISTING +ve x and z.

\bold{=  > 4y + 8 = }{\bold{\red{4(y + 2)}}}
