Question

Solve for k.
4 - 2k = -5(k + 7)

Answer 1

4 - 2k = -5(k + 7)

First, expand. / Your problem should look like: 4 - 2k = -5k - 35
Second, add 5k to both sides. / Your problem should look like: 4 - 2k + 5k = -35
Third, simplify 4 - 2k + 5k to 4 + 3k. / Your problem should look like: 4 + 3k = -35
Fourth, subtract 4 from both sides. / Your problem should look like: 3k = -35 - 4
Fifth, simplify -35 - 4 to -39. / Your problem should look like: 3k = -39
Sixth, divide both sides by 3. / Your problem should look like: k =
`-(39)/(3)`
Seventh, simplify
`(39)/(3)` to 13. / Your problem should look like: k = -13

Answer: k = -13
