I really don’t understand this please help me !!!!

PART BPMichael=3g+12PKensley=4g+8To find when they have equal amount of points just set each equation equal to each other. 3g+12=4g+8 moving all g variables to one side and all constants to the other side3g+12-3g-8=4g+8-8-3g now we have;g=4 so when they each score 4 goals their point total will be the same. Doing systems of equations we generally set it up this way;3g+124g+8Now subtract one equation from the other;g=4 same result just a slightly different style of doing it.PART CTo find the number of goals for when Kensley begins to outscore Michael, we already know when they have 4 goals each they are equal in points. Let’s find that value;3(4)+12=244(4)+8=24So logic tells us if at 4 goals they are equal in points, then at 5 goals I bet Kensley overtakes Michael. Let’s find out;3(5)+12=274(5)+8=28So Kensley outscores Michael at 5 goals! Hope this helps you understand better! Any questions please feel free to ask! Thanks and have a great day!
