Q.
25
=

+
15
(
n
−
1
)
25=2+15(n-1)
25
=
2
+
15
(
n
−
1
)
solve for
n
n
n
Distribute and Simplify:
Simplify the right side of the equation by distributing
15
15
15
into
(
n
−
1
)
(n-1)
(
n
−
1
)
.
\newline
25
=
2

15
n
−
15
25 = 2 + 15n - 15
25
=
2
+
15
n
−
15
\newline
Combine like terms on the right.
\newline
25
=
15
n
−
13
25 = 15n - 13
25
=
15
n
−
13
Combine Like Terms:
Isolate the variable term
15
n
15n
15
n
by adding
13
13
13
to both sides.
\newline
25
+
13
=
15
n
25 + 13 = 15n
25
+
13
=
15
n
\newline
38
=
15
n
38 = 15n
38
=
15
n
Isolate Variable Term:
Solve for
n
n
n
by dividing both sides by
15
15
15
.
n
=
38
15
n = \frac{38}{15}
n
=

n = 2.5333
n
=
