Chapter 2 - Section 2.1 - Linear Equations in One Variable - Exercise Set: 34

Answer

$x=-1.5$

Work Step by Step

We are given that $2.4(2x+3)=-.1(2x+3)$. We can first use the distributive property to simplify both sides. $2.4\times(2x+3)=-.1\times(2x+3)$ $4.8x+7.2=-.2x-.3$ Add .3 to both sides. $4.8x+7.5=-.2x$ Subtract 4.8x from both sides. $7.5=-5x$ Divide both sides by -5. $x=-1.5$
