2(k - 5) + 3k = k + 6 |
Use the distributive property to simplify and combine like terms. |
2k - 10 + 3k = k + 6 |
Combine like terms. |
5k - 10 = k + 6 |
Then, add 10 to both sides. |
5k = 16 + k |
Then, subtract k from both sides. |
4k = 16 |
Then, divide both sides by 4 |
k = 4 |
CHECK your solution by plugging back into the original equation. |
