✏️ORDERED PAIR
Problem:
- Is the ordered pair (-7, -3) a solution of x +y = 10?
Solution:
- If an ordered pair is a solution to an equation, Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
- [tex]x + y = 10[/tex]
- (-7, -3)
- Now substitute all the given
- [tex] - 7 + ( - 3) = 10[/tex]
- [tex] - 7 - 3 = 10[/tex]
- [tex] - 10 = 10[/tex]
So therefore, - 7 and - 3 are not solution
