Question

What is the missing value?

Answer 1

The missing value is 5.

Step-by-step explanation:

Given,

5x-2y = 30

And x = 8 ( as per the solution)

To find the value of y

Putting x=8 in the given equation we get,

5×8 - 2y = 30

or, 40-30 = 2y

or, 2y = 10

or, y = 10÷2

or, y = 5

Hence,

The solution will be (8,5)

Answer 2

Answer:

I believe that the missing value is 5, y=5

Step-by-step explanation:

1st since you can see in the ordered pair that 8 is in the x place that means 8 is the x value so what you can do is rewrite the equation to look like this: 5(8)-2y=30

2nd solve for y

5(8)-2y=30

40-2y=30

-40. -40 -subtract 40 on both side

-2y=-10

÷-2. ÷-2 -divide -2 on both sides

y=5
