Question

How do we get , K = 7 from evaluating this

2k + 2 = 3k - 3 and 9k = 7k + 7

Answer 1

Hey!!

$2k + 2 = 3k - 3$

Bring the like terms in left and Right hand side


$= > 2k - 3k = - 3 - 2 \\ \\ = > - k = - 5 \\ \\ = > k = 5$

And

$9k = 7k + 7$
Bring the like terms in left and Right hand side


$= > 9k - 7k = 7 \\ \\ = > 2k = 7 \\ \\ = > k = \frac{2}{7}$


Hope it helps!
