Chapter 2 - Section 2.1 - Linear Equations in One Variable - Exercise Set: 85

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 $K=-11$.
