(7n-1)/(8)=6
Okay,
I think I add 1 to both sides, so now I have..
(7n)/(8)=7
And then, to get n by itself I divide 7 into both sides, so now I have..
n/8=1
n=1 is what I get, but I'm not sure, could someone please check this for me?
No. Hang your head in shame :)
Multiply both sides by 8
7n-1=48
add one to each side, then divide each side by 7
No ,
first you multiply each side by 8 to get
7n - 1= 48
now add 1 to each side
7n = 49
divide both sides by 7
n = 7
check: in original
((7(7) -1 1)/6
= (49-1)/6
= 48/8
= 6
Check!!
Ohhh,
thanks you very much,
I wasn't sure which step I did first.:)
To solve the equation (7n-1)/8 = 6, you've correctly started by adding 1 to both sides to isolate the term with n:
(7n - 1)/8 + 1 = 6 + 1.
Next, simplify:
(7n - 1)/8 + 1 = 7.
Now, to get rid of the fraction, multiply both sides by 8:
((7n - 1)/8 + 1) × 8 = 7 × 8.
Simplifying further:
7n - 1 + 8 = 56.
Combine like terms:
7n + 7 = 56.
Subtract 7 from both sides:
7n + 7 - 7 = 56 - 7.
Simplifying further:
7n = 49.
Finally, to solve for n, divide both sides by 7:
(7n)/7 = 49/7.
Simplify:
n = 7.
Therefore, the value of n that satisfies the equation (7n-1)/8 = 6 is n = 7.
