20? I’m not for sure maybe look in the book? That’s the answer I got and it was right
-x + 5y = 8
multiply this equation by 3
-3x + 15y = 24
now add it to the other equation ( elimination)
-3x + 15y = 24
3x + 7y = -2
-----------------------
0x + 22 y = 22
divide each side by 22
y =1
substitute into -x + 5y =8 to find x
-x + 5(1) = 8
-x + 5 = 8
-x =3
divide by -1
x =-3
Answer (-3,1)
Choice A
Answer:
(1,-1)
Step-by-step explanation:
y < 4x+5
x = 1, y = -1 => -1 < -4+5 (T)
