When solving absolute value equations, how would i solve 15 - 2k = 45?

15-2k = 45

+2k = + 2k

15 = 45+2k

-45 = - 45

-30 = 2k

/2 = / 2

-15 = k

15-2 (-15) = 45

15-2k=45

Subtract 15 on both sides so you're left with letters on one side and on the other side numbers. So that would be -

-2k=45-15

-2k=30

Now you divide both sides by two so you get k on it's own and it's value on the other side. So that would be -

k=-15

So k equals - 15.
