A = 16 over 49
b= 2 then 1 over 10
Answer:
Hello,
<u>k=-3 and h=-2</u>
Step-by-step explanation:

h+1 is thus a root of x²+(-3-1)*x-5=0
x²-4x-5=0
x²+x-5x-5=0
x(x+1)-5(x+1)=0
(x+1)(x-5)=0
h+1=-1
<u>h=-2</u>
Answer: x = 12 and y = -8
Explanation:
x + y = 4
4x + 3y = 24
———————
-3(x + y = 4)
4x + 3y = 24
———————-
-3x - 3y = -12
4x + 3y = 24
———————
x = 12
If x = 12
x + y = 4
12 + y = 4
y = -8
