Answer:X=5/6 Y=8/5

Step-by-step explanation:

-6x +5y=3

+6x

5y=6x+3 (divide each number by 5)

Y=6/5x + 3/5 (Plug that into your x equation)

12x+15 (6/5x + 3/5) =34

(Multiply 15 by the numbers in the brackets you can break it down and do 15•6 divided by 5 )

15•6=90 divided by 5=18x

15•3= 45 divided by 5=9

(Add like variables)

12x+18x=30x

30x+9=34

(Subtract 9 from itself do the same to 34)

9-9= 0

34-9=25

Divide 30 by itself to get x by itself then divide 25 by 30

25 divided by 30= 5/6

X=5/6 (plug that into the y equation)

Y=6/5•5/6+3/5

Multiply 6/5 and 5/6 straight across because this is multiplication you don't need like denominators

6/5•5/6=30/30=1

Y=1+3/5

1/1 + 3/5

Here you need to have like denominators because it is addition so just use 5

5•1=5

5/5+3/5=8/5

Y=8/5

I got (-6.28, -0.76). 

Step 1.) Write out the problems
   -2x=8-6y
   -15x=21-6y

Step 2.) Pick a problem and solve for X
   -2x=8-6y =  x=-4-3y

Step 3.) Plug in the x
    (-15)(-4-3y)= 21-6y
    60 + 45y= 21-6y

Step 4.) Solve for y
    y=-0.76

Step 5.) Plug in the y value into one of the equations
    -2x= 8- 6(-0.76)
    -2x= 8 + 4.56
     x= -6.28

Step 6.) Check your answers
    -2(-6.28)=8-6(-0.76)
    12.56=12.56

Step 7.) Write it out
   (-6.28,-0.76)
