Answer 1

Jessie instaled axels on 23 cars

The equation: 2·j = 46

Explanation:

j - total number of cars she installed axles on

2 - number of axles she installed on one car

2·j - total number of axles she installed on

46 - total number of axles she installed on

2·j = 46 {divide both sides by 2}

j = 23
