3x+4y=-23
2y-x=-29
what is the (x, y) solution to the system of equations above?

x=7

y= -11

Step-by-step explanation:

3x+4y= -23    equation 1

2y-x= - 29     equation 2

using equation 2 we have:

2y +29 = x    equation 3

using equation 3 in equation 1 we have:

3x+4y= -23  

3(2y +29) +4y = -23

6y + 87 +4y =-23

10y +87= -23

10y = -23-87

10y = -110

y= -110/10

y= -11

so we have:

2y +29 = x

2(-11) +29 = x

we have:

x= 7

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
