Answer

$w=-2$ and $w=.8$

Work Step by Step

We are given that $|5w+3|=7$. Therefore, $5w+3=7$ and $5w+3=-7$ We can solve each equation to find the solutions. For $5w+3=7$, first subtract 3 from both sides. $5w=4$ Divide both sides by 5. $w=.8$ For $5w+3=-7$, first subtract 3 from both sides. $5w=-10$ Divide both sides by 5. $w=-2$
