K=?

Answer 1

8

Is the answer .................................

Answer 2

8(10-K) = 2k

mutiply the bracket by 8

(8)(10)= 80

(8)(-k)= -8k

80-8k= 2k

move -8k to the other side

sign changes from -8k to +8k

80-8k+8k= 2k+8k

80= 2k+8k

80= 10k

divide by 10 for both sides

80/10= 10k/10

k= 8

Answer: k= 8
