Answer:
x = 1
y = -3
Step-by-step explanation:
We have the value of x in terms of y already, so our first step will be to plug in y + 4 for x in the first equation. This gives us:
[tex]y + 4 = 2y + 7[/tex]
From here, we can just solve for y:
[tex]y + 4 = 2y + 7\\4 = y + 7\\-3 = y[/tex]
And now that we know y = -3, we can solve for x using the second equation:
[tex]x = y + 4\\x = -3 + 4\\x = 1[/tex]
Lastly, we should just double check our answers using the first equation to see if they work:
[tex]1 = 2 * -3 + 7\\1 = -6 + 7\\1 = 1[/tex]
It does!
