Answer:
Infinitely many solutions.
Step-by-step explanation:
2x+y=3
6x=9-3y
-------------
y=3-2x
6x=9-3(3-2x)
6x=9-9+6x
6x=6x
infinitely many solutions

Longest side
Hence this is an acute triangle.
Answer:
10 + 30x
Step-by-step explanation:
Answer:
No solutions: 7−5+3x−1= 3x + 7
One solution: 7−5+3x−1= 2x + 4
Infinitely Many Solutions 7−5+3x−1= 3x + 1
Step-by-step explanation:
No solutions means it results in no x and a false statement like 3 = 0.
One solution means it results in x = a number.
Infinite solutions means its results in no x and in a true statement like 3=3.
- So to get No solutions: 7−5+3x−1= 3x + 7
This will eliminate the x and result in 1 = 7 which is false.
- One solution: 7−5+3x−1= 2x + 4
This will result in x= 3
- Infinitely Many Solutions 7−5+3x−1= 3x + 1
This will eliminate the x and result in 1 = 1 which is true.
