Solutions

Expert Solution

Given x= -2 

           y=-3

           z=5 

a) 3x-3y , Putting the value of x and y in the expression

   =  3(-2)-3(-3)

   = 3

b) -2(y-z) , Putting the value of y and z 

    = -2(-3-5)

    = 16

c) -(-2y+z)-(3/2 x²) , Putting the value of x ,y and z 

    = -(-2(-3)+5)-(3/2 (-2)²)

    = -5

Hence , the values are 3 , 16 and -5.

The Required solutions are :-

a) 3

b) 16

c) -5
