## anonymous 4 years ago can someone guide me the right way please? use set-builder notation to write the solution set 3y + x = 4 x = 2y − 1

1. KingGeorge

Do you know what set-builder notation?

2. anonymous

Zed if i can get your assistance real quick it would be helpful

3. anonymous

if it has an infinite number of solutions

4. anonymous

is that what you meant King?

5. anonymous

or if I know what set builder notation is?

6. KingGeorge

what the notation actually is.

7. anonymous

no it doesn't say

8. anonymous

do I just plug in the 2nd equation into the first?

9. KingGeorge

have you seen solutions posted in a similar fashion to these?$\left\{ x, y \in R: x, y > 0 \right\}$$\left\{x, y \in R: x \geq 5, y < 0 \right\}$

That's what set-builder notation looks like.

As for solving the equation itself, plugging the 2nd equation into the first should work.
