Question

Find an ordered pair (x,y) that is a solution to the equation

-x+5y=4

Answer 1

- x + 5 y = 4 (x = 6)

- ( 6 ) + 5 × 2 = 4 (y = 2)

- 6 + 10 = 4

4 = 4

∴ (6, 2) is an ordered pair that is a solution to the given equation .

Answer 2

(1, 1 )

Explanation:

choose any value of x to substitute into the equation and solve for y

choosing x = 1 , then

- 1 + 5y = 4 ( add 1 to both sides )

5y = 5 ( divide both sides by 5 )

y = 1

then (1, 1 ) is a solution to the equation
