Does the ordered pair (−5,−5) satisfy the following system of equations?<br> {−3x−3y=125x+5y=−20
FrozenT [24]

Well, let's see. The problem gave you an ordered pair. In other words, you have an 'x' and a 'y' coordinate. All you need to do is put them into the equation.

Step-by-step explanation:

This means that instead of --

-3x - 3y = 125 + 5y = -20

We would have:

-3(-5)-3(-5) = 125(-5) + 5(-5) = -20

From here, you just simplify it into:

30 = -650 = -20

Since the values are not the same, the ANSWER is NO. The ordered pair does not satisfy the following system of equations.

Answer:

All integers are whole numbers

Step-by-step explanation:
