Question

The ordered pair (1, 4) is a solution to the equation x + y = 5 because 1 + 4 = 5 is a true statement. Which of the following ordered pairs is also a solution to the equation x + y = 5 ?(- 3, - 2)(2, 3)o (- 4, 1) (0, - 5)

Answer 1

Given

The ordered pair (1, 4) is a solution to the equation x + y = 5 because 1 + 4 = 5 is a true statement. Which of the following ordered pairs is also a solution to the equation x + y = 5

Solution

`\begin{gathered} x+y=5 \\ \text{The ordered pair (1,4)} \\ \therefore x=1\text{ and y = 4} \\ 1+4=5 \\ \\ \text{NOW } \\ (2,3)\text{ Which is (x,y)} \\ x+y=5 \\ 2+3=5 \end{gathered}`

The final answer

`(2,3)`
