sommersquid 2 years ago What is the value of the x variable in the solution to the equations? 3x + 2y = 6 2x + 3y = −1

1. across

Multiply the first equation by 3, multiply the second equation by -2, add the two results, and solve for x.

hello across!!

3. sommersquid

why do you use 3 and -2? :/

4. across

If you do it, then you'll see why I used those numbers.

8. sommersquid

thats what i got for both

9. sommersquid

what do i do now?...

So you got\begin{align}9x+6y&=18\\-4x-6y&=2\end{align}Now add them:$5x=20$Can you solve for $$x$$?

yes x = 4 :) thank you so so much :3
