-8x=56 a value of x that makes the equation true is _ which one substituted into the equation and simplified makes the equation turn into _=_ a value of x that makes the equation false is _ which one substituted into the equation in simplified makes the equation turn into _=_

1 answer

To solve the equation \(-8x = 56\):

  1. Divide both sides by -8: \[ x = \frac{56}{-8} = -7 \]

So, a value of \(x\) that makes the equation true is \(-7\).

Substituting \(-7\) into the equation: \[ -8(-7) = 56 \] When simplified: \[ 56 = 56 \]

Now, let's find a value of \(x\) that makes the equation false. Any value of \(x\) that is not \(-7\) will make the equation false. For example, let's use \(x = 0\).

Substituting \(0\) into the equation: \[ -8(0) = 56 \] When simplified: \[ 0 = 56 \]

Thus:

  • A value of \(x\) that makes the equation true is \(-7\), which when substituted into the equation and simplified turns into \(56 = 56\).
  • A value of \(x\) that makes the equation false is \(0\), which when substituted into the equation and simplified turns into \(0 = 56\).
