You would basically go back and trace all your steps, that's what I do. And if your answer seems reasonable then you have the right answer but if your work doesn't match the answer than you've messed up.
I hope I helped if I did like my answer and comment down below thx
I don’t know about y but x=35 they are diagonal from one another so they will be the same
Answer:
x = 2 
Step-by-step explanation:
-26 = -15x + 8
-34 = -15x
x = 2 
(y + 7)(y + 7)
49 is a perfect square of 7
it can also be written
(y + 7)²
hope this helps :)
SOLUTION:
GCF = 2
= 6y^3 + 10n^2
= 2 ( 3y^3 + 5n^2 )
Hope this helps! :)
Have a lovely day! <3
