Ryan, jessica, and mark each solved this system of equations. all of their answers are different. find and explain the mistakes. what is the correct answer?
y = 3x + 2
6x – 2y = 10
ryan’s
ryan solved by adding the equations. he says the solution is ((7)/()/(2))
y = 3x + 2 →
3x + y = 2
6x – 2y = 10 →
3x – y = 5
6x = 7
y= - 3/2
jesse’s
jesse used matrices. she says the solution is ((7)/()/(2))
[the rest of jesse's problem is posted below along with mark's graph]
mark’s
he graphed the equations. the lines are parallel and do not intersect, so there is no solution.
