Question

What is the solution of the system?

Answer 1

You can solve the system by isolating the same variable in both equations, then setting those equations equal to each other. For instance, say we isolate y:

$4x+3y=12$
$3y=12-4x$
$y=4- \frac{4}{3} x$

Do the same for the other equation, then set both equations equal to each other. You can then solve for x. Once you have a value for x, you can plug it into either of the original equations and find y!
