X=-3x+20
Add 3x to both sides to move the -3x over
4x=20
Then do 20 divided by 4
X=5
Answer:
+9or -9 is the answer ☺️ you
I don't understand this work sorry.
The answers are x=4 for question one and question two is x=0
You find the midpoint by using the formula m=(x1+x2 then divide by 2, and y1+y2 divided by 2) that’s how you find midpoint and the (5,13) 5-x1 13-y1 and so on hope this helps!
