1) Transform the inequality into equation by replacing "<" or ">" with "=":
-2x - 4 > 8
-2x - 4 = 8
2) Simply solve for x:
-2x - 4 = 8
-2x = 8 + 4
-2x = 12
x = -6
3) Now do the following exactly the same: first, look into the symbol that you have replaced (">" or "<"). Put the same symbol into your answer "x = -6":
x > -6
4) Now, look which symbol was in front of "x" in the original inequality (-2x - 4 = 8). If it is "+" (for example, 4x, 0.01x) leave "x > -6". If it is "-" (for example, -3x, -0.04x) change ">" into "<" or change "<" into ">" (put the opposite symbol).
5) You have -2x in the original inequality - then, in "x > -6" change the symbol into "<". So, your answer will be
x < -6 or the option 1.
Hope this helps!

Answer:

B will be the answer...

Step-by-step explanation:

The second equation in system B is only in terms of y, so we need to use elimination to eliminate the x term from the second equation in system A.

To do that, we need to multiply the first equation by 5.

5 (-x − 2y = 7)

-5x − 10y = 35

Add to the second equation.  Notice the x terms cancel out.

(-5x − 10y) + (5x − 6y) = 35 + (-3)

-16y = 32

Combining this new equation with the first equation from system A will get us system B.

-x − 2y = 7

-16y = 32
