Answer:
x^3+4x^2+5x+2
Step-by-step explanation:
Step-by-step explanation:
multiply the first equation by 1, the second by -1 and add.
x + 2y = -16
-x - 6y = 28
--------------------
0 - 4y = 12
-4y = 12
y = -3
x + 2×-3 = -16
x - 6 = -16
x = -10
(2x-24)/8
the only way to simplify it is divide every number by 2
(x-12)/4=(1/4)x-3
