Question

Identify the values that create ordered pairs that are solutions to the equation 3x-5y=20

Answer 1

`(5,-1)`

`(10,2)`

Explanation:

we have

The ordered pairs that are solutions to the equation
`3x-5y=20` are

`(5,y),(x,2)`

Step 1

Substitute the value of x of the first ordered pair and solve for y in the equation

`3(5)-5y=20`

`5y=15-20`

`y=-1`

The first ordered pair is
`(5,-1)`

Step 2

Substitute the value of y of the second ordered pair and solve for x in the equation

`3x-5(2)=20`

`3x=20+10`

`x=10`

The second ordered pair is
`(10,2)`
