Question

3(k+5)+6k=-2(3k-6)-1

Answer 1

k = -(4/15)

Explanation:

3(k+5)+6k=-2(3k-6)-1

3k + 15 + 6k = -6k + 12 - 1

[Expand brackets]

9k + 15 = -6k + 11

[Combine like terms]

9k +6k + 15 = -6k + 6k + 11

[Add 6k to both sides]

15k + 15 = 11

[Combine like terms]

15k + 15 - 15 = 11 - 15

[Subtract 15 from both sides]

15k = -4

[Combine like terms]

k = (-4/15)

[Divide both sides by 15]
