Answer
$K=-11$
Work Step by Step
We are given the equation $3.2x+4=5.4x-7$ and the equation $3.2x=5.4x+K$
In order to find the value of K that makes both equations equivalent, we must move all constant terms in the first equation to the right side.
For $3.2x+4=5.4x-7$, subtract 4 from both sides.
$3.2x=5.4x-11$.
Therefore, both equations will be equivalent when $K=-11$.
