Question

Find a solution to the linear equation y=−x+7 by filling in the boxes with a valid value of x and y.

Answer 1

Answer:

$(x,y) = (0,7)$

$(x,y) = (3,7)$

Step-by-step explanation:

The question and the attached image are different. However, the attached image answers the question y = -4 correctly.

So, I will solve for: $y = -x + 7$

Given

$y = -x + 7$

Required

Possible values of x and y

Let x = 0:

$y = -x + 7$

$y = -0 + 7$

$y = 7$

So, we have:

$(x,y) = (0,7)$

Let y = 4

$y = -x + 7$

$4 = -x + 7$

Collect Like Terms

$x = -4 + 7$

$x =3$

So, we have:

$(x,y) = (3,7)$

So, all you need to do is: assume a value for either x or y, then solve for the other variable.
