Chapter 2 - Section 2.1 - Linear Equations in One Variable - Exercise Set: 98

Answer

$x=9.62$

Work Step by Step

To solve $1.25x-20.175=-8.15$, you need to get $x$ by itself on one side of the equation. To do this, you first need to add 20.175 to both sides. $(1.25x-20.175)+20.175=-8.15+20.175$ $1.25x=12.025$ Then, you need to divide both sides by $x$'s coefficient, $1.25$. $1.25x\div1.25=12.025\div1.25$ $x=9.62$
