Answer:
D
x >= -8
multiply by 2
-X <= 8
divide by -1
X >=-8 (remember flip sign if multiply by negative)
Step-by-step explanation:
Line up the equations and add them up, adding the x's together then y's (which should cancel out) then the totals.
Then the equation should equal -9x=36 and when tou solve x= -4.
Plug -4 in for x in one of the equations, I chose the second one, and solve.
y = -21
Hope this helps! :)
The answer should be D bc the others don’t make sense. Hope this helps!
