Answer:

\text{B. }(2, -3)

Step-by-step explanation:

\begin{cases}y=2x-7,\\y=-x-1\end

Since y=y:

2x-7=-x-1,\\3x=6,\\x=2

Solving for y:

y=2(2)-7=4-7=-3

Verify that the point of intersection occurs at \boxed{(2, -3)}\checkmark

3x+2y= -19 solve by elimination of addition<br> -3x-5y= 25
tensa zangetsu [6.8K]

Answer:

x=-5, y=-2

Step-by-step explanation:

3x+2y= -19  

-3x-5y= 25

Add the two equations together

3x+2y= -19  

-3x-5y= 25

------------------

0x -3y = 6

Divide each side by -3

-3y/-3 = 6/-3

y = -2

Now find x

3x+2y = -19

3x +2(-2) =-19

3x-4 = -19

Add 4 to each side

3x -4+4 = -19+4

3x= -15

divide by 3

3x/3 = -15/3

x = -5

What is the qoutient of -18÷ (-1 over 6) ?
topjm [15]
...
When you divide a negative integer by a negative, it becomes a positive.  Also, when you have a problem like this...-18/-1/6, you switch the -1 and 6, leaving us -18/-6, but also, in the process of flipping the two numbers, we change to -18*-6.  Henceforth...-18/(-1/6)=-18*-6=108.
