Answer:
(4,-3)
Step-by-step explanation:
Multiplying the bottom equation by -6, we get -6x+12y=-60.
Adding this to the first equation gives 15y=-45, and thus y=-3.
So, it follows that 6x+3(-3)=15, and thus x=4.
You get a "sum" when you add numbers together.
It’s 20f-30g I just took that question on a test
Say if you wanted to find factors of 6, the you'd multiply that number by any number to find a factor or multiple.
