Answer:

-0.7

Step-by-step explanation:

$x-y=0.7$

You can choose any digits you wish for $x$ and $y$ but the difference must be 0.7. I chose 1.0 and 0.3.

$x=1\\y=0.3\\x-y=0.7\\\\y-x=\\0.3-1=\\-0.7$

I need help with the steps. The answer is (5,2)

Elden [556K]

So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

$y+3+y=7\\2y+3=7\\2y=4\\y=2$

Next, now that we have the value of y, substitute it into either equation to solve for x:

$x+2=7\\x=5\\\\x=2+3\\x=5$

<u>And this is how you get your final answer (5,2).</u>
