Question

1. x – 5y = -15
Complete the missing value in the solution to the equation (-5, ____)

Answer 1

(-5,2)

Explanation:

We are given that

`x-5y=-15`

We have to find the missing value in the solution to the equation (-5,_).

We have to find the value of y when x=-5

Substitute x=-5 in the given equation

Then, we get

`-5-5y=-15`

[tx]-5y=-15+5=-10[/tex]

`y=(-10)/(-5)=2`

Hence, the value of y=2

Then ,solution of the given equation is (-5,2) .

Answer 2

x - 5y = -15

(-5, y)

-5 is in the x place, and so replace x with -5

-5 - 5y = -15

-5y - 5 = -15

-5y - 5 (+5) = -15 (+5)

-5y = -10

-5y/(-5) = -10/(-5)

y = 2

(-5, 2) is your answer

hope this helps
