Abed says he has written a system of two linear equations that has an infinite number of solutions. one of the
equations of the system is y = 3.x - 1. which could be the other equation?
y = 3.x + 2
3x - y = 2
3.x - y = 1
3x + y = 1

Adding and subtracting matricesfind the value of each variable. x = and y = would
