y = –1/2x + 4
x + 2y = –8
How many solutions does this linear system have?

one solution: (8, 0)
one solution: (0, 8)
no solution
infinite number of solutions

Respuesta :

y = -1/2x + 4 . . . . . . . . (1)
x + 2y = -8 . . . . . . . . (2)
putting (1) into (2), we have
x + 2(-1/2x + 4) = -8
x - x + 8 = -8
8 = -8
Therefore, the system has no solution.
