Answer:
x > 
Step-by-step explanation:
given
2x > 7 ( isolate x by dividing both sides by 2 )
x > 
The linear combination method is the same as the elimination method. Let's multiply the second equation by -2 so the x terms cancel each other out. When we do that we get a system of

and

. The x-terms cancel each other out giving us

and y = -3. Now sub -3 into one of the equations to solve for x. x+2(-3)=-4, and x - 6 = -4. x = 2. So the solution for our system is (2, -3)
It is C. floor 20 and floor c have the same amount of tenants
the slope of the given point is m=−3/4
