X+y=10 and 2x+4y=30<br>What are the steps to solve this equation?

Ronch [10]

Answer:

x=5 and y=5

Step-by-step explanation:

You "plug" one equation into the other, to get a new equation that only has one variable (x or y), then you can simplify that and have your answer.

So let's plug the first into the second:

First, we convert the first equation into an x=... form. For this one, this means moving the +y to the other side:

x = 10 - y

Now we substitute 10-y for x in the second equation:

So 2x+4y=30 becomes:

2(10-y) + 4y = 30

And simplify that:

20 - 2y + 4y = 30

20 + 2y = 30

2y = 30-20

2y = 10

y = 5

This is the first answer! If we put this into the first equation, we get:

x = 10 - 5 = 5

Now we have both answers, x=5 and y=5

To get a free meal at his favorite restaurant,Tom needs to spend 50$ or more at the restaurant. He has already spent 30.25$. How

andrey2020 [161]

So for Tom to get his free meal he needs to spend 50 dollars.

This means the following⬇️

$50 - 30.25$
This equation is the 50 dollars he has to spend minus the 30.25 he has already spent which results in⬇️
$= 19.75$
This results in Tom needing to still spend 19.75 more dollars to get his free meal!!

Hope this helped!!
