Answer:

x=2

y= -3

Step-by-step explanation:

3x+2y=0    2y=-3x, y=-3x/2

3x-15y=51

substitute y

3x-15(-3x/2)=51

3x+45x/2=51

multiply by 2

6x+45x=102

51x=102

x=2

y= -3

Answer:

x=2

y=-3

Step-by-step explanation:

Ok so....

Since this problem is practically set up all you have to do is solve it! So what i did was try to cancel both of the x's so that I am just left with the y. I subtract everything and end up with

17y = -51

Now, all you have to do is divide giving you the answer for y which is

y = -3

Next, you have to plug in the value of y to either the first equation or second equation in the question. I chose the first equation and once I plugged it in it looked like this.

3x - 6 = 0

Now, add 6 to both sides giving you

3x = 6

Now all you have to do is divide

x = 2

TAADAA!!!

If you want to check your answer if you're unsure just plug in both values to either the first equation or second equation in the original problem. Okay well have a good day!! :D
