Equation setup:
Set up the equation from the given problem.
\newline
(
4
k
−
10
)
/
k
=
8
(4k - 10) / k = 8
(
4
k
−
10
)
/
k
=
8
Eliminating the fraction:
Multiply both sides of the equation by
k
k
k
to eliminate the
fraction
.
k

(
4
k

10
k
)
=
k
×
8
k \times \left(\frac{4k - 10}{k}\right) = k \times 8
k

(
k
4
k
−

)
=
k
×
8
Simplifying the equation:
Simplify both sides of the equation.
4
k
−
10
=
8
k
4k - 10 = 8k
4
k
−
10
=
8
k
Combining like terms:
Subtract
4
k
4k
4
k
from both sides to get all
k
k
k
terms on one side.
\newline

k
4k - 10 - 4k = 8k - 4k
4

k
Further simplification:
Simplify the equation after subtraction.
\newline
−
10
=
4
k
-10 = 4k
−
10
=
4
k
Dividing both sides:
Divide both sides by
4
4
4
to solve for
k
k
k
.

-10 / 4 = 4k / 4
−

=
4
k
/4
Finding the value of k:
Simplify the division to find the value of k.
\newline
k
=
−
10
4
k = \frac{-10}{4}
k
=

k = -2.5
k
=
−
