Answer:
a = 2/k -3 or
a = (2-3k)/k
Step-by-step explanation:
k = 2 /(a+3)
Multiply each side by (a+3)
k * (a+3)= 2 /(a+3) *(a+3)
k(a+3) = 2
Divide each side by k
k/k(a+3) = 2/k
a+3 = 2/k
Subtract 3 from each side
a+3-3 = 2/k -3
a = 2/k -3
If we need a common denominator on the right, multiply 3 by k/k
a = 2/k -3k/k
a = (2-3k)/k
