Answer:
No solutions .........
Step-by-step explanation:
3x-4y=7
-12x+16y=10
Multiply 1st equation by 4, you get:
12x-16y=28
Add the 1st and 3rd equations:
0x+0y=38
0(x+y)=38
(x+y)=38/0 which is undefined
This is a scalene triangle because all of the angles are different, and scalene triangles have no equal sides.
