Answer:

To find the ordered pairs that are solutions to the equation X+2y=8, we need to isolate the variable y on one side of the equation.

We can start by subtracting X from both sides:

X+2y = 8

X+2y-X = 8-X

2y = 8-X

Now we can divide both sides by 2:

y = (8-X)/2

So the ordered pairs (X, y) that are solutions to the equation X+2y=8 are the ones that satisfy the equation y = (8-X)/2.

We can substitute any value of x into the equation and find the corresponding y value.

For example, if we take X= 4, we can find the corresponding y value:

y = (8-4)/2 = 4/2 = 2.

so (4,2) is a solution to the equation X+2y=8.

We can also plot the equation on a Cartesian plane and find the points where the equation is true, those are the solutions.

Alternatively, we can solve the equation for X and find the solutions for y.

X = 8-2y

So the ordered pairs (X, y) that are solutions to the equation X+2y=8 are the ones that satisfy the equation X = 8-2y

We can substitute any value of y into the equation and find the corresponding X value.

For example, if we take y= 2, we can find the corresponding X value:

X = 8-2(2) = 8-4 = 4.

so (4,2) is a solution to the equation X+2y=8.

In this case, any value of X and y that satisfies the equations y = (8-X)/2 or X = 8-2y are solutions to the equation X+2y=8
