To solve this, we need to use the distributive property for the right side of the equation. -2(7 + 2k). To do this, we multiply the outside number by the inside number(s). -2(7) + -2(2k) = -14 + (-4k) Now our equation is 3k = -4k -14. Add 4k to both sides to get k on one side. 7k = -14 Divide by 7 to get k. k = -2. I hope this helps!
