Sagot :
Answer: K = -7
Explanation:
22k - 39 = 11k + 20k + 24
22k - 39 = 31k + 24
22k - 31k = 24 + 39
-9k = 63
K = -7
Explanation:
22k - 39 = 11k + 20k + 24
22k - 39 = 31k + 24
22k - 31k = 24 + 39
-9k = 63
K = -7
Answer:
[tex]k=-7[/tex]
Step-by-step explanation:
[tex]22k-39=11k+2\left(10k+12\right)[/tex]
Apply the Distributive Property
[tex]22k-39=11k+20k+24[/tex]
Combine like terms
[tex]22k-39=31k+24[/tex]
Rearrange variables to the left side of the equation
[tex]22k-31k=24+39[/tex]
Combine like terms
[tex]-9k=24+39[/tex]
Calculate the sum or difference
[tex]-9k=63[/tex]
Divide both sides of the equation by the coefficient of variable
[tex]k=-\frac{63}{9}[/tex]
Cross out the common factor
[tex]k=-7[/tex]
I hope this helps you
