Question 104811: I need help solving these equations- the last two I need to solve and graph. getting started on the 1st one I got as far as 21k-15 =12 I am thinking that the solution would be 3k. On the 2nd question- arrived at: 15-5x < 3x-9, where do I go from here? Last: Not sure how to solve the last one. Please help!

3/4 (7k - 5)=12

Question 104867: I am having trouble understanding this math. Can you please help me with this problem maybe I will understand it.
I need to identifi the terms, like terms, coefficients, and constant terms. Then simplify the expression. I have tried to do it and am not sure I an doing it right. The problem is
-4k - 12 + 3k
The answers I have are Coefficient = 4 and 3 the term = -4k, 12, and 3k
the constant term = 12 the like term is -4k and 3k
to simplify the equation
-4k - 12 + 3k
(-4k) - 12 + (3k)
(-4k + 3k) - 12
(-1k) (-12)
-12k
