14:9
Answer:
Let the original number be x
Successor is defined as the number which comes immediately after a particular number.
also, the successor of a whole number is the number obtained by adding 1 to that number.
Then, the successor of a number x is, x+1
As per the given condition :
we have;

Using distributive property on LHS (i.e,
)
Then, we have
5x+5+x=83
Combine like terms;
6x+5=83
Subtract 5 from both the sides we get;
6x+5-5=83-5
Simplify:
6x=78
Divide both side by 6,

Simplify:
x =13
Therefore, the original number x is, 13
Answer:
25
Step-by-step explanation:
Answer:
(0,6)
Step-by-step explanation:
The given system of equations is

and

We substitute the first equation into the second equation to get:

We expand to get:

We group similar terms to get:



Put x=0 in to the first equation to get:

Therefore the solution is (0,6)
5/9(f-32)=c
5/9f+5/9*-32=c: step 1
5f/9-160/9=c: step 2
5f/9-160/9+160/9=c+160/9: step 3
5f/9=160/9*9+c*9: step 4
5f/5=160/5+9c/5: step 5
f=32+(9c/5): answer
