Question

3-x-3x=5 how is it -0.5 THATS what Photomath says but I don’t get how

Answer 1

Answer:

Step-by-step explanation:

3-x-3x=5

first combine like terms

3-4x=5

-4x=2

divide each side by -4

x=2/-4 or -1/2 or -0.5

Answer 2

Answer:

x = -0.5

Step-by-step explanation:

We are given the equation 3 - x - 3x = 5, and we need to solve for x.

First, let's isolate the variable, which means to bring all the non-x terms to one side and all the x terms to the other side. To do so, subtract 3 from both sides:

3 - x - 3x = 5

-x - 3x = 5 - 3

-x - 3x = 2

Now, we need to combine -x and -3x. Remember that this is basically the same thing as:

- (x + 3x) = - (4x) = -4x

So, -x - 3x = -4x

Set this equal to 2:

-4x = 2

Divide both sides by -4:

x = 2 / (-4) = -1/2 = -0.5

Therefore, the answer is -0.5.
