Solve for z. 8z − 4 = 7z

aleksandr82 [10.1K]

8z − 4 = 7z

move 8z to the other side

8z-8z-4=7z-8z

-4= 7z-8z

Y=x^2-2x-1 and y=-3x+5 solved algebraically

eduard

Answer:

Step-by-step explanation:

y=x²-2x-1

and y=-3x+5

x²-2x-1=-3x+5

x²+x-6=0

x²+3x-2x-6=0

x(x+3)-2(x+3)=0

(x+3)(x-2)=0

x=-3,2

when x=-3

y=-3×-3+5=9+5=14

when x=2

y=-3×2+5=-6+5=-1

so solutions are (-3,14) and (2,-1)
