Answer:k = </span>

<span>
Explanation:To get the value of k, we will need to isolate it on one side of the equation.
This can be done as follows:
d = a(2+kt)
<u><em>1- get rid of the brackets using distributive property:</em></u>
d = a(2+kt)
d = 2a + akt
<u><em>2- Subtract 2a from both sides of the equation:</em></u>
d - 2a = 2a + akt - 2a
d - 2a = akt
<u><em>3- Divide both sides of the equation by "at":</em></u>

Answer:yes
Step-by-step explanation:
You have to simplify each equation
7m +6 - 5 = 15 2m + 5 = 9
7m + 1 = 15 2m = 4
7m = 14 m = 2
M = 2
They both end up with the same answer so they are equivalent
