Question

How many solutions will this system of equations have?

y = 3.5x - 3.5
y = -3.5x + 3.5

No solution

Infinite solutions

One solution

Two solutions

Answer 1

infinite solutions

Answer 2

Why do you say infinite?

Answer 3

Infinite is wrong...just sayin.

Answer 4

When you don't know the rules just don't say it. It is correct.

Answer 5

why do you say infinite? When you solve for x you get 1.

Answer 6

3.5x-3.5=-3.5x+3.5
3.5x+3.5x=3.5+3.5
7x=7
x=1

Answer 7

So, how would it be no solution?

Answer 8

look it's like\[\frac{ a1 }{ a2 } = \frac{ b1 }{ b2 } = \frac{ c1 }{ c2 }\] then the pair of equations have infinite many solutions

Answer 9

so now we have no solution, infinite solutions, but you can solve it for x. I don't understand how you can solve it for x and there is not a solution. you need to explain that please.

Answer 10

So, what is the REAL answer to this problem?

Answer 11

oh, yes it,s unique solution. i m really sorry.
as here
\[\frac{ a1 }{ a2 } \neq \frac{ b1 }{ b2 }\]

i didn't see it really sorry.

Answer 12

So it does have 1 solution, then?

Answer 13

x=1...one solution. I'm sticking with that. Don't see how I am incorrect.

Answer 14

Alright I'll let you two know.

Answer 15

One solution is correct!

Answer 16

Thank you...for the confirmation and the medal.

Answer 17

I'm not a math teacher for nothing....
