What is the answer to 36n - 72 = 4 + n/6?

Question

and can u explain how u got the answer please!?

Answer 1

36n - 72 = 4 + (n/6); first step is to group the n-terms:
36n - n/6 = 76. Now eliminate the denominator on the left side: 216n - n = 6*76 ==> 215n = 456, and isolate the n: n = 456/215

Answer 2

With equations, what you do on one side, you must do on the other side. That is the key to solving equations. Addition is the opposite of subtraction and multiplication is the opposite of division.

Step 1: Group the terms.

36n - n/6 = 4+ 72.

Note that when we grouped the terms, whatever the sign was in the original problem of the terms that we brought over to the other side was changed. So -72 becomes +72 on the right side, and +n/6 becomes -n/6 on the left side.

36n-n/6 = 4+72
36n-n/6 = 76

We must eliminate the fraction. We do so by multiplying both sides by -6. We use -6 because -n/6 is really -1/6 n.

[36n-n/6] *-6 = 76 * -6
-216n+ n = -456
-215n = -456
-215n/-215 = -456/-215
n=2.121(rounded)

We divided both sides by -215 so that we could isolate the variable, n. We divided because -215n is really -215 times n. And the opposite of multiplication is division.

Our answer is n=2.121, which is rounded.

Answer 3

36n - 72 = 4 + n/6
So 36n = 72 + 4 + n/6
So 36n - n/6 = 76
So 35 5/6n = 76
n = 76/ 35 5/6
n = 6 x 76 / 135
n = 456/135
n = 3 51/135
n = 3 17/45

Answer 4

as far as i know,

36n - 72 = 4 + n/6
36n - n/6 = 4 + 72
(36n*6)/6 - n/6 = 4+72
216n/6 - n/6 = 76
215n/6 = 76
215n = 456
n = 2.121 (rounding)

Answer 5

36n-72=4+n/6
*6 *6
216n-432=24+n
-n -n
215n -432=24
+432 +432
215n=456
/215 /215
n=2.12 approximately

Answer 6

36n-72=4+n/6
36n=4+n/6+72
36n=76+n/6

damn its been so long sorry.. im stuck ..
