Question

solve for k.
8 + 5k = -10 + 9k - 10
k = \boxed{}

Explanation:

Step1: Combine constants on right

$-10 - 10 = -20$, so equation becomes:
$8 + 5k = 9k - 20$

Step2: Subtract $5k$ from both sides

Isolate $k$ terms on one side:
$8 = 4k - 20$

Step3: Add 20 to both sides

Isolate the $4k$ term:
$28 = 4k$

Step4: Divide by 4 to solve for k

$\frac{28}{4} = k$

Answer:

$7$
