Question

Can someone help? I don't understand.

Answer 1

Hence missing value in the solution to the equation is:(-5,2)

Step-by-step explanation:

We are given the equation:

$x-5y= -15$

and we need to complete the missing value in the solution to the equation

(-5,?)

Since the solution is in the form of ordered pair, so first value represent value of x and second value represents value of y i.e (x,y)

So, x= -5, Now finding y:

Putting value of x in given equation:

$x-5y= -15\\-5-5y= -15\\-5y=-15+5\\-5y=-10\\y=-10/-5\\y=2$

So, value of y is 2

Hence missing value in the solution to the equation is:(-5,2)
