I got 7 if you are trying to look for the value of x than you multiply the bottom by two to have the y's equal. It should be
3x+2y=25
12x-2y=80
Since the twos mark each other out it would be
3x=25
12x=80
You add the top and bottom so it becomes one like this
15x=105
Divide 15 on both sides and it should give you 7.
X=7

Answer:
(-6,-1)
Step-by-step explanation:
let b be x2,y2
then apply mid point formula
x=(x1+x2)/2
y=(y1+y2)/2
V=(1/3)(area of the base)(<span>altitude)
V=</span>(1/3)(6²)(6)= 72 m³
Hope this helps :3
