Tell them that, just like one variable equations, systems of equations can also have either one solution, no solution, or infinitely many solutions. Point out that in the previous activity, each of the three systems of equations had one solution, which they found algebraically by solving the system, and so the graphs of the equations of the ...

Aug 06, 2020 · Putting the value of b in equation (ii), we get a = 5 (1) = 5. Hence, the given system of equations will have an infinite number of solutions for a = 5 and b = 1. (ii) We have, 3x + y = 1, 3x + y − 1 = 0 …. (i) (2k – 1) x + (k – 1) y = 2k + 1. ⇒ (2k – 1) x + (k – 1) y – (2k + 1) = 0 …….
