Y = –6x+2 –12x – 2y = –4 how many solutions does this linear system have?

Asked by maham237 @ in Mathematics viewed by 358 People

y = –6x 2 –12x – 2y = –4 how many solutions does this linear system have? one solution: (0, 0) one solution: (1, –4) no solution infinite number of solutions

Answered by maham237 @


Y = -6x + 2 . . . . . . . . (1)
-12x - 2y = -4 . . . . . . (2)
Putting (1) into (2), we have
-12x - 2(-6x + 2) = -4
-12x + 12x - 4 = -4
-4 = -4

Therefore, the system has infinite number of solutions.
