10. acme car rental charges $4 a day plus $0.15 per mile,
whereas interstate rental agency charges $20 a day and
$0.05 per mile. how many miles must be driven to
make the daily cost of an acme rental a better deal than
an interstate rental?

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
