Question

Identify the values that create ordered pairs that are solutions to the equation

3x - 5y = 20.

(5,y) (x,2)

Answer 1

(5, -1)(10, 2) are solutions to this equation

Answer 2

The values that create ordered pairs that are solutions to the equation :

3x - 5y = 20.

(5,y) = (5,-1)

(x,2) = (15,2)

Explanation:

Given :

3x - 5y = 20

(5,y)

Put x = 5, y = y in the given equation:

`3* 5 - 5y = 20`

`-5y=20-15`

`-5=5y`

`y=-1`

(5,y) = (5,-1)

(x,2)

Put x = x, y = 2 in the given equation:

`3x - 5y = 20`

`3x-5* 5=20`

`3x=20+25`

`3x=45`

x = 15

(x,2) = (15,2)
