Solve for c

14 + (-12) = - 12 + c

solve for k

- (k + 12) = 6 + (-12)

(two questions)

Solve for c

add like terms

get 2 = c - 12 then add 12 to both sides

+12 + 12

so c = 14

solve for k

first distribute and add like terms

-k - 12 = - 6 add 12 to both sides

get - k = 6 multiply both sides by - 1

k = - 6
