X = 6iy-4y+83-66i/13
y= 14+9i/2-x-3xi/2
Answer:
D
Step-by-step explanation:
Consider the equation:

Use distributive property in both sides:

Separate terms with x into the left part and terms without x into the right part:

Since you get true equality 0 = 0, the equation is true for all real values of x. So, the equation has infinitely many solutions.
Answer: 7
Step-by-step explanation:
rearrange the equation to where you set it equal to 0 by moving the 25 over.
n2 - 8n -9 = 0
now factor
(n-9)(n+1)
so n1 = 9
n2 = -1
