Answer:

Step-by-step explanation:

8 - 24k + 1 = -25 - 7k

-24k + 9 = -25 -7k

-17k + 9 = -25

-17k = -34

k = 2

answer is D

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{k = 2}}}}}[/tex]

Option D is the correct option.

Step-by-step explanation:

[tex] \sf{8(1 - 3k) + 1 = - 25 - 7k}[/tex]

Distribute 8 through the parentheses

[tex] \longrightarrow{ \sf{8 - 24k + 1 = - 25 - 7k}}[/tex]

Add the numbers : 8 and 1

[tex] \longrightarrow{ \sf{9 - 24k = - 25 - 7k}}[/tex]

Move 7k to left hand side and change it's sign

Similarly, move 9 to right hand side and change it's sign

[tex] \longrightarrow{ \sf{ - 24k + 7k = - 25 - 9}}[/tex]

Collect like terms

[tex] \longrightarrow{ \sf{ - 17k = - 25 - 9}}[/tex]

Calculate

[tex] \longrightarrow{ \sf{ - 17k = - 34}}[/tex]

Divide both sides by -17

[tex] \longrightarrow{ \sf{ \frac{ - 17k}{ - 17} = \frac{ - 34}{ - 17} }}[/tex]

Calculate

[tex] \longrightarrow{ \sf{k = 2}}[/tex]

Hope I helped!
