    1.) 300 - 5w = 150

    2.) 30 weeks

    Step-by-step explanation:

    w = weeks on the diet

    if every week he's on the diet, that means that the weeks * 5 is how many pounds he loses. If he's on the diet one week then he loses 5 pounds. 2 weeks then 10 pounds ... etc. But because he's losing punds the value is negative

    He starts at 300 pounds so the y-intercept (starting value) would be 300

    Finally, because he's looking to get to 150 pounds, that is the final value you're solving for

    So this is your firat equation:

    300 - 5w = 150

    Then we are looking for when two different eqaution have the same value.

    Your equation is: 60 + 7w

    Her equation is: 120 + 5w

    Your final equation is 60 + 7w = 120 + 5w

    Solve for this by getting w on one side, and your plain old variable-less value on the other. Do this by subtracting 5w from each side, as well as 60.

    Your equation is now 2w = 60

    Then divide the whole equation by 2, and you get w = 30
