Answer:

x= 66.5

Explanation:

  1. First you write them down like this:

Hours Weeks

19 - 2

x - 7

2.Then you cross multiply, to make an equation so the equation will be:

2x=19*7

3.Then19*7 is 133 so then the equation gets simplified to:

2x=133

4.Now you divide both sides by 2 because that is how many x's there are.so it will be 133/2=66.5 and the equation is now completed to x= 66.5 !
