Whatis another way to say 2x = -3 - 15

5 answers

You can simplify the equation \(2x = -3 - 15\) to \(2x = -18\). Another way to express the equation is by stating it as:

\[ 2x + 18 = 0 \]

or by rearranging it:

\[ x = \frac{-18}{2} \]

which simplifies to

\[ x = -9 \].

So, one alternative way to present the original equation is \(2x + 18 = 0\).

What about 2x + 18 = 3?

If you want to express the equation \(2x + 18 = 3\) in another form, you can rearrange it by isolating \(x\):

  1. Subtract 18 from both sides:

    \[ 2x = 3 - 18 \]

    This simplifies to:

    \[ 2x = -15 \]

  2. Now, divide both sides by 2 to solve for \(x\):

    \[ x = \frac{-15}{2} \]

So another way to express the original equation could be:

\[ 2x + 15 = -3 \]

or

\[ x = -7.5. \]

Hence, there are multiple ways to represent the equation depending on how you choose to manipulate it!

I meant -3 not 3

Got it! If you have the equation \(2x + 18 = -3\), you can rewrite it in several ways. Here’s how to manipulate and express it:

  1. Subtract 18 from both sides:

    \[ 2x = -3 - 18 \]

    This simplifies to:

    \[ 2x = -21 \]

  2. Divide both sides by 2 to solve for \(x\):

    \[ x = \frac{-21}{2} \]

So, some alternative forms of the original equation \(2x + 18 = -3\) could be:

  • \(2x + 21 = 0\)
  • \(x = -10.5\)
  • \(2x = -21\)

All of these represent the same relationship from different perspectives!
