Answer:
Step-by-step explanation:
Y = –x + 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
Y = - x + 4 x + 2 ( -x + 4 )=-8 x- 2 x + 8 = -8 - x = - 8 - 8 - x = - 16x = 16 y = - 16 + 4y = - 12 The system has one solution ( x, y ) = ( 16, - 12 ).
