Question

DECIDE WHEATHER THE ORDER PAIR(-3,-5) IS A SOLITION OF THE EQUATION 7X-5Y=15

Answer 1

(-3, -5) is not a solution of the equation 7x - 5y = 15

Explanation:

1) Knowing that coordinates are given to us as (x, y), plug in the ordered pair into the equation.
`7(-3)-5(-5)=15`

2) Do PEMDAS on the left side of the equation

1. 
   `-21+25=15`
2. 
   `4=15`
3. 
   `4\\eq 15`

Answer 2

Not a solution

Explanation:

Hello!

We can determine if it's a solution by plugging in the x and y-values of the point into the equation. If both sides are equal to each other, then it is a solution.

-3 is the x-value and -5 is the y-value, since an ordered pari is written in the form of (x,y).

Evaluate

• 7x - 5y = 15
• 7(-3) - 5(-5) = 15
• -21 + 25 = 15
• 4 ≠ 15

Since both sides are not equal to each other, (-3,-5) is not a solution.
