Answer:
B
Step-by-step explanation:
To rewrite the equation x + y + 3 = -2x + 4y + 18, first combine like terms.
x + y + 3 = -2x + 4y + 18
3x - 3y + 3 = 18
3x - 3y = 15
This is the standard form.
It can also be simplified by dividing each term by 3 to x - y = 5.
So what you need to start with is taking the x from both sides as adding 12 to them. Then, you move the 27 over 4 decimals.
The midpoint is (7,4.75) so the y-coordinate should be y=4.75. I hope that helps
