Can someone pls help me im stuck

A:     x + y = 2  

       -3x-y=5

        -2x+0=7

         x=-3.5

         Once you get the x plug it into one of the X variables and you will end up with y= 5.5

B y= -27/4 x= -19

That's all :)

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

y -5 = (-1/4)(x + 8)
