Answer 1

$210-45x=390

x=-4

The luggage weighted -4(5)=20

Explanation:

x is the price for every 5lbs of luggage.

x=−4

Step 1: Simplify both sides of the equation.

210−45x=390

210+−45x=390

−45x+210=390

Step 2: Subtract 210 from both sides.

−45x+210−210=390−210

−45x=180

Step 3: Divide both sides by -45.

−45x

/−45

=

180

/−45

x=−4
