Answer 2

Answer:

$x=20; y=50$ or $(20, 50)$

Step-by-step explanation:

Substitution means plugging in one variable's value that consists of the opposite variable. Because $y=3x-10$ is already specified, you can plug it into the second equation's $y$ value. After doing that, it looks like this:

$-4x+2y=20→-4x+2(3x-10)=20$

Then you would distribute the $3$ across the parentheses next to it, like this:

$-4x+2(3x-10)=20→-4x+6x-20=20$

Then, add like terms, like this:

$-4x+6x-20=20→2x=40$

Then divide both side by $2$ to isolate $x$.

$x=20$

Now, you can plug $20$ ($x$) into either equation, but the first one seems simpler so you would pick that. It would look like this:

$y=3x-10→y=3(20)-10$

Solving would look like this:

$y=3(20)-10→y=60-10→y=50$

So the answer is $x=20; y=50$ or $(20, 50)$.
