1. 3x-10=x+70
+10 -x
2x=80
x=40
2. x+27+2x-39=180
3x-12=180
+12
3x = 180
x = 64
3. 2x ÷ 80=5x+44
- 2x -44
36= 3x
12=x

(4.5,-7)
Step-by-step explanation:
you add the x coordinates then divide them by 2
And then add the y coordinates then divide them by 2 also
X= 12

9+3 and -3 + 3 the three is negative because you drop the minus sign down
This cancels out the three and 9+3 is 12 so X=12
Step-by-step explanation:
28,4 most likely I think
