Each of the ordered pairs given in the answer choices represent (x, y). Plug each pair of numbers into the equation to see if it is the solution.
y= -6x + 1
A) (-2,13)
13= -6(-2) + 1
13= 12 + 1
13= 13
Yes, this is a solution
B) (-1,7)
7= -1(-2) + 1
7= 3 + 1
7= 4
No, this is not a solution
C) No, it cannot be both since B is not a solution
D) No, it cannot be neither since A is a solution
ANSWER: A) (-2,13) is the solution
Hope this helps! :)
You can separate the parts of the expression to make it easier to solve.
8/-2= -4
2/5(/)1/5= 2/5 (you could just do 2/1= 2 and put 5 as the denominator)
-4 2/5
That is a mixed number, with an integer and a fraction. It cannot be simplified any more.
I hope this helps!

Answer:
3
if a is 1 more than b it can be expressed as so:
a=b+1
b+1=a
b^2+1=a^2
b^2=a^2-1
b=a-1
if b if 1 then a is 2
b+1=a
-a+b=-1
a-b=1
a=2, b=1
a=b+1
a+b=3
1+2=3
