Well using elimination is easy because they basically did it for you.
4x-5y=-6
2x+5y=12
The postive 5y and negative 5y cancel out because -5y plus 5y is zero.
so you are left with
4x=-6
2x=12
Add these together
6x=18
divide both sides by 6 and Solve to find your x
x=3
Now we have to eliminate x to find y.
we multiply the second equation by -2 so it can cancel out so
(2x+5y=12)-2
-4x-10y=24
Add the equations together
4x-5y=-6
-4x-10y=24
You are left with -15y = 30
Solve for y
y = -2
So your final answer for the elimination would be
(3,-2)
<span>C) buyers are aware of the accurate measurements of the property.
A residential survey is also known as a boundary survey and is used to determine the boundaries of a piece of property. It is generally required as part of the process of building new construction on a property to insure that the construction doesn't cross the property line and intrude on someone else's property. With this in mind, only option "C" reflects what a residential survey is.</span>
