Question

How many solutions does the following equation have?

3x + 6 = 3(x + 2)

Answer 1

factor the 3 on the right side and solve for x
3x+6 = 3x +6
everything cancels out and your left with no solution

Answer 2

. A. exactly 2 solutions
B. exactly 1 solution
C. infinitely many solutions
D. no solutions
Those are the choices

Answer 3

infinitely many

Answer 4

So, its no solution?

Answer 5

you can plug in any number and the equation will equal

Answer 6

yea 3x - 3x = 0
so your left without a variable
therefore its no solution

Answer 7

How many do you want?

Answer 8

Im confused.. gettin' three different answers.

Answer 9

What do you mean Cliffsedge?

Answer 10

Plug in any number you want for x and see if it works.

Answer 11

Okay

Answer 12

@Kashan and @jayz657 are both incorrect.

Answer 13

@jayz657 and @Kashan thats not right. the equation has infinitely many solutions. you can plug in infinitely many numbers and always get 0=0, which is true

Answer 14

It can't be "no solution". Here's a counter-example showing why

3x + 6 = 3(x + 2)

3*0 + 6 = 3(0 + 2) ... Plug in x = 0

0 + 6 = 3(2)

6 = 6 .. which is TRUE

So clearly x = 0 works and it is a solution

Answer 15

Logic FTW.

Answer 16

Ohh, so it is infinity ∞ ?

Answer 17

X may be any real number as a solution.

Answer 18

Ok thanks guys.
