how to find x

\[\color{#C00}{2x} = y\]\[6x + 4\color{#T00}{\cdot y} = 6x + 4\cdot \color{#C00}{2x}\]

how to find x? cause to find y you need to know x right?

The first equation we have is 2x = y, that is the same as y=2x. The second equation we have is 6x + 4y = 14. Now, we put y=2x into the second equation. That is whenever we see "y" in the second equation, we rewrite it as "2x" So, we get: 6x + 4 (2x) = 14 Can you solve this?

You know that \(2x = y\), right? So can you say that \(6x + 4y =14\) can be written as \(6x + 4(2x) = 14\)?

Hmm... yes!

dumbsearch2 Group TitleBest ResponseYou've already chosen the best response.0
so y = 2! so y = 2, and x= 1! no?

Sorry, it's not \(6x + 4y = 14\). I got my reply wrong :P
