Question

3x-x-5=2(x+2) -9 please help

Answer 1

Answer:

Infinitely many solutions valid for x.

Step-by-step explanation:

For this problem, let's attempt to solve for x:

3x - x - 5 = 2(x + 2) - 9

2x - 5 = 2x + 4 - 9

2x - 5 = 2x - 5

2x = 2x

x = x

Note, that since this problem has reduced to the equation x = x, this means that it doesn't matter what value x holds, this equation will always be true.

To answer this question, we can simply say there are infinitely many solutions that the value x can hold which will make this equation true.  (I.e., x will always be equal to x)

Cheers.

Answer 2

Answer:

infinite solutions

Step-by-step explanation:

Simplify 3x-x-53x−x−5 to 2x-52x−5.

2x-5=2(x+2)-92x−5=2(x+2)−9

2 Expand.

2x-5=2x+4-92x−5=2x+4−9

3 Simplify 2x+4-92x+4−9 to 2x-52x−5.

2x-5=2x-52x−5=2x−5

4 Since both sides equal, there are infinitely many solutions.
