Dad is 4 times as old as his son jim. in 10 years, dad's age will be 20 years more than twice jim's age. how old is jim? if d = dad's age now and j = jim's age now, which of the following systems could be used to solve the problem? d = 4j and d + 10 = 2j + 20 d = 4j and d + 10 = 2(4j + 10) + 20 d = 4j and d + 10 = 2(j + 10) + 20

Matt and brian were solving a system of equations. they both noticed that the two lines had the same slope. brian said that because each line in the system had the same slope, the two lines had to be parallel, which meant the solution to the system was "no solution" matt disagreed, and said they should also look at the y-intercepts before determining how many solutions there were. who is correct?
