Answer:
the number is X=2
Step-by-step explanation:
Suppose number is X
8X-1 =X+13
8X-X= 13+1
7X=14
X=2
Answer:
8n-1= 13+n is the equation, n=2 is the answer for the variable.
Step-by-step explanation:
8n-1= 13+n
Move the variable to one side.
8n-1= 13+n
-1n -1n
7n-1= 13
Now, add to both sides, since that is the opposite of subtracting.
7n-1= 13
+1 +1
Then, divide to both sides by 7 to leave the variable by itself.
7n= 14
7 7
n= 2
