Question

NEED THIS DONE PLEASE HELP!!! ONE MEDAL
Which is a solution of the equation?

2x + y = 5

Answer 1

y = 5-2x

Answer 2

This equation has infinite solutions.

In order to solve it, we can assume x = constant = c

Then y = 5 - 2x = 5 - 2c

So solution set is (x,y) = (c, 5 - 2c), with c is a real number.

Some examples in this set may be:

(1, 3); (0, 5); etc.
