How to solve an equation like -2k+6+3=30

k = 10.5 or k = -

(solved for k)

Step-by-step explanation:

1. Add the numbers (-2k + 6 + 3 = 30) --> (-2k + 9 = 30)

2. Move the constant to the right and change it's sign

(-2k + 9 = 30) --> (-2k = 30 - 9)

3. Subtract the numbers (-2k = 30 - 9) -->  (-2k = 21)

4. Divide both sides by -2 to isolate 'k'.  (-2k = 21) --> * k = - *

Hope this helps :)
