Q:

20 points..Please Help!! What does it mean for an equation to have no solution or infinite solutions? Identify the equation with one solution, infinite solutions and no solutions: (you don’t need to come up with an exact answer:• 6y+2=3y+4 4x + 4y + 8 = x + y + 2 5x – 3 = 5x - 2

Accepted Solution

A:
Hello!

If a problem has infinite solutions you will end with a 0, with one it will end with any number and for no solutions you will get a equations that does not equal each other

Ex: 5 = 9

You can do the bottom first since it looks the easiest.

5x - 3 = 5x - 2

subtract 5x from both sides

0x -3 = -2

Add 3 to both sides

0x = 1

0x [tex] \neq 1[/tex]

So it has no solutions

Next you can do the top one

6y + 2 = 3y + 4

subtract 3y from both sides

3y + 2 = 4

Subtract 2 from both sides

3y = 2

Divide both sides by 3

y = [tex] \frac{2}{3} [/tex]

Since this came to a regular number it has one solution

The only one left has the be the one with infinite solutions by we can check

4x + 4y + 8 = x + y + 2

since the left side is the same as the right just multiplied by 4 it has infinite solutions

So the first one has one solution

The second one has infinite solutions

And the third one has no solutions

Hope this helps!
