−7x−12=_____x+12

whats the missing number i want the correct answer

1 answer

To solve the equation \(-7x - 12 = __ x + 12\), we can isolate the variable \(x\) on both sides.

  1. Let's move \(-12\) to the right side:

    \[-7x = __ x + 12 + 12\]

    This simplifies to:

    \[-7x = __ x + 24\]

  2. Now, we need to find the missing coefficient. For the left side to equal the right side, we can equate the coefficients of \(x\).

    \[-7x = __ x\]

    This tells us that the missing coefficient must be \(-7\).

So the completed equation is:

\(-7x - 12 = -7x + 12\)

Thus, the missing number is \(-7\).
